This only took me minutes to install and it works as described. I am perfectly happy with my purchase.
Ricky C.
Works great. I am amazed how much a difference it made. I also made a hood around the saw, but it hardly needs it with dust collector. The extra depth from removing factory dust shoot helps out a lot with a small shop. I am really impressed!
David w.
It was easy to install works great.i think it will hold up well
Frank M.
fits perfectly
Jim V.
Could not use my current miter saw blades.
Justin M.
Works much better than the stock dust collection!
Michael G.
Product arrived on time and was easy to install. Works very well and leaves minimal dust. Definitely would recommend!
Donald A.
Product is made well and works great. The installation video skips over that the screws holding blade guard are extremely hard to remove and that you have to remove the spring loaded middle piece by squeezing and pulling out. Without doing that, you can’t get a tool in to remove the 2nd screw at all. The video needs improved.
Cynthea F.
It works! Now I just have to remember to turn on my vacuum!
Thank you!
John B.
I asked about a part that appears to be unlike the one shown in the installation video. No one has gotten back to me.
Michael R.
Product is very well made and professional looking.
Install went very fast and easy.
It collects about 90% of the chips/dust produced, which is is a 90% increase from what the stock dust collector achieved Overall a great product and would definitely buy again
Kory H.
It’s better than the factory dust collection but still allows a ton of dust. I think the whole module is flawed because the port is so small it just doesn’t allow a decent amount of suction to collect enough dust. Don’t think it’s the part or the design, but the necessary requirements of the saw itself and how it works. Plus the rubber part was torn about 2 cuts into use. Not sad I tried it and will continue to use it, but, I wouldn’t buy it again.
Jolene G.
I’m relatively new to woodworking but love using my miter saw.
I don’t have a T20 or T30 driver in all my stuff so that was extremely frustrating trying to figure out how to make that work. I needed 3 hands to get the screws back in but after a few scraped knuckles and ugly words I did it.
So far the dust collection does seem to be better. Thanks!
Christine P.
Send the right one. multiple emails were sent with no responce !!!!we ordered a 780 and a 715 showed up. If I don’t hear from you, I will be disputing this on my credit card and giving bad reviews on every website. Thanks for not being a stand up company.
Michael M.
Works better than expected
Michael J.
I believe the mounting of the rubber shroud to the plastic saw dust collection piece near the blade is dangerous. The 4 small screws holding the rubber to the collection piece seems very flimsy and not securely attached. I will be attaching a vacuum to the hose which I believe will get in the way of my cutting. I have yet to actually try it. I hope not. I may end up putting the original Dewalt piece back on the machine. We shall see. Jury is still out.
Brian W.
Same as all the other low reviews. The main part broke during normal usage.
I’d be inclined to give it another shot if Travis made it right by replacing that part, but I don’t see the point in spending money on something that is not designed to withstand the rigors of the tools its manufactured to be used with. I had really enjoyed shopnation content and hoped the business would have been run in a way that would meek me proud to support.
Nancy H.
Dust collection is so much better. Easy to install.
David H.
The installation of the dust collector on my DeWalt 12" compound saw limits the cutting capacity of the saw. I was not aware of this until after I installed it. It also requires the removal of a factory installed part that you cant reinstall with the dust collector. Not sure what that part was for. It does reduce the amount of saw dust flying around when you are cutting 6x6 posts for deck columns.
KEVIN L.
It was easy and fir perfectly.
I lost the QR code so I watched another woodworker's video of how to install it, just to see how easy it was for him. EASY
The screws that hold the lower blade guard on were very very tight. Not anyone's fault.
The rubber flap slot with the screws...one screw began to crack along the grain of the 3D printed "grain". But I left it snug, and it's fine.
PERFECT.
I'm very happy.
Tim A.
Installed easy, works great.
Jim W.
Collects 90% more dust than the stock DeWalt dust collection bag.
Donald L.
Easy install. Haven’t used it yet.
Nate F.
It’s ok, it reduces some dust but when you cut larger pieces like 2x10 it’s almost like nothing is there. It’s an improvement over out of the box but just mildly. One major disappointment is that when changing the blade it does get in the way. You have to be careful not to break it or bend your blade being replaced. An annoyance nothing major though. Would I purchase again if I got another saw? Probably not
MarkandBecky T.
Much better than the Dewalt design
STEVEN B.
It’s much better than before not perfect but I’m happy. One thing I like also with the old standard duct collection that the saw come with I was able to slide it back closer to the wall with the new system, I had more room.
David I.
I was a little weary about purchasing it as I have a 780 type 20 and was not sure if it would work or not. The available install video answered a lot of questions and it was easily installed. I have not had a chance to use it as of yet but the saw is prepped and ready for the next job. I'm happy so far
Linus F.
Works great
Doug K.
This was a replacement for one that a flying cutoff piece broke.
Garrett D.
Caught 95% of the sawdust from my DeWalt saw. Hope that it is eventually available as injection molded, rather than 3D printed. Was able to put a dust collection hood behind the saw so they the remaining 5% of dust falls into a bucket. Vast improvement over my previous dust collection method.
Steve R.
Just installed yesterday, easy peasy. Hooked to DeWalt shop vac. Chopped a couple of 2x4's, and minimal sawdust escapes.
Zachary G.
So far this seems to do a lot better than the stock dust collection, though don't expect a miracle. When I was cutting aluminum it still got everywhere, but I think that's basically unavoidable and this system is more for sawdust.
The only major drawback for me so far is that it seems like the blade can't be changed without removing it since it gets in the way. That means vs. the stock system it's much more of a pain to change your blade with this on. Though it's possible I'm missing something that would make it possible.
Rob B.
Thanks again for your help Great product.
Brian D.
It works better than expected! I would definitely buy again
Kenneth S.
What an improvement! Following the video made installation a snap. I use a shop vac for dust and collection improved immediately and significantly. Way better than DeWalt's stock system. A "must have" in my book! Thanks!

I’ve paired it with a dedicated shop vac and the dust box is powered by a 4” dust collection system. Overall it’s good but not great. I’d say it picks up marginally more than the original collector. I might put the larger flexible shroud back on the original collector and see what happens.
Ralph O.
Fit well. My saw was not exactly like the video. But it was not difficult to figure out
Jacques D.
Easy installation
Mark O.
Install was a snap. So so so much less dust.
S. E.
It's hard to gauge how much sawdust a miter saw puts out, but it's a lot. And as anyone who owns one knows, the OEM "dust collection system" on a DWS780 is a screen door on this otherwise formidable submarine.
As I cut now, I can see the vast majority of the sawdust being sucked up by the shop vac: We've replaced the screen door with a hatch. Well done, Shop Nation.
William G.
The first exhaust system was destroyed when a piece of wood I was cutting kicked back. Still don't know what happened but the plastic ended up in millions of pieces. Luckily I wasn't injured. The new exhaust system is up and running OK. Still have considerable dust to deal with but nothing like not using it at all.
David N.
Simple installation, looks like it was an OEM part. I have only made one quick cut with it so far. I did not have any kind of dust collection hooked up and it still reduced the amount of dust in the air.
Adam L.

Daniel P.
100% better than the stock dust tube!
Only thing is, on mine the twist to lock for the 2.5in fitting is really loose. I just used a few wraps of thread tape to make it snuggle.
Brady K.
The installation video is a little dicey, I didn't know what a T20 is but I found a bit for the screw. When I pulled off the old dust collection, I couldn't believe how much dust was stuck in the pipe, even though I had a hose connected to it. The new one you could clearly feel the suction coming through and I would say it reduces the dust by about 60-70% with some kicking off to the sides.
I like it, now do something for my delta T725 table saw
Kirk F.
It does improve dust collection
Shaun B.
I need to remove the rear blade guard from my saw - which is fighting me. I reached out to Support but they have not responded - I’d say 10 days at this point. The unit is not yet installed as a result. May adjust my review once it actually works.
ALLAN S.
Still leaves a mess but less than the OEM
Paul E.
Very happy with my purchase. This dust collection replacement is superior to DeWalt's original system for two reasons. First, it collects more dust and second, it allows your saw to sit closer to the back wall.
Fan Z.
I’m the occasional diy-er so I don’t use the miter saw much but previously I had to wheel it outside from my garage to my backyard and wood dust would fly everywhere. I’ve tried with a dust collector and the OEM simply didn’t have a good collection. I upgraded to the Shop Nation one and made myself a zero clearance plate and it’s a huge difference. Now I just turn on the dust extractor, and cut in my garage! Thanks!
Ken G.
Miles better than the factory dust collector.
Sanford W.
It does pick up a lot more of the dust than the old DeWalt shoot however it seems to throw a lot of material back at me and lands on top of my miter saw. Good product I like it
Paul H.
Works great also saves about 5 to 6 inches off distance saw needs against the wall.
Peter M.
Works great, huge improvement. Simple install. What's not to like.
James H.
Simple to install and very efficient in dust collection when in use.
Doug S.
The dust collection chute installed perfectly on my DeWalt miter saw. I noticed an immediate reduction in the amount of dust generated in the air.
Thomas C.
Worked great.
Paul S.
Fairly easy to install. Hooked up my dust extractor and away the sawdust disappeared. Beats the OEM dust port hands down.
Rod C.
The first one broke. We’ll see how long this one lasts.
Rod
Yurie R.
Very easy to install. Attaching the flexible tubing is a bit of a chore and I wish there was a bit more bite for those rubber skirt screws (I realize they'd become a potential friction/collection point for dust). But it has drastically reduced the amount of wood particles on the floor behind my chop saw.
Sean M.
Nice and easy to install and use. I have to say, I wish they would include a step by step DOCUMENT in the packaging instead of only a QR code to a video that does the step by step, but that's a personal preference (since I also have tools running and prefer to have the instructions with me while I'm installing), but the process was super easy and the installation video was incredibly easy to follow.
Donald H.
Really glad I upgraded. The vacuum hose connects so much more easily, and the dust collection is absolutely superb!
MICHAEL G.
Worked better Thank you. I expected.
Nijaz M.
Initially I thought it wasn’t working like I’ve seen on videos because I saw some larger wood chips coming off to the side. But when I tested my miter saw without it almost instantly my lungs told me “you fool, this is actually working and it’s taking away the most important dust which is the fine stuff”. So yes this stuff works and is worth it. Elevates the tool tenfold.
Steven R.
Works great!!!
Roger S.
If fits great, haven't used it yet.
Jack V.
I felt like the rubber sheet should have came down about an inch or 2 lower so it could catch the dust when or slightly before I start cutting. Great concept though.
Michael L.
This is the 2nd one I bought because the 1st one crack at a few of the hole. I made new holes but it didn’t hold up so I had to buy another. I’d like the plastic to be a little more durable. When it’s on and working there is a much improved dust collection so no doubt abut that. That I give 4 1/2 stars. I would recommend to purchase it… that’s why I bought another one.
William B.
Fit perfectly, easy to install. Combined with a zero clearance baseplate, really reduces sawdust!
Charles R.
Works great, easy to install.
Tom R.
Did not work as well as advertised
THOMAS N.
I was on for where the other side wasn't going to be with it. It was! I like it so much there will be ways to get where the dust had stuck in the way. My squirrel overlord told me that I should get him a soda and hotdog from the gas station.
Peter S.
So this dust collector is awesome. I gladly ripped the factory “system” out and quickly installed the new one. Got the vac hooked back up and in business. Absolutely zero dust is on the bench. Great engineering!
Isaac S.
It is definitely better than the stock dust collector port. Like all dust collection it's not a 100% but it is considerably better. I also like that it moves with my sliding miter saw.
Roy M.
Great product
Paul
Your dust collection is a huge improvement over DeWalt’s.
Ronny C.
No problem changing out the old collector. Took about 30 minutes and it was up and running. I know I will enjoy not having to vacuum so much. Thank you.
Frank
Easy install. YouTube video available showing step by step installation instructions. Does a great job of collecting saw dust.
Rusty G.
So I was a little hesitant when I first installed it in my shop, but once I out actually using out it out in the field on job site it does wonders and worth every penny. And I don’t look back cutting the factory out and tossing it. Now to add to some other saws. So using slider I thick boards you have some restrictions but if it eating dust I ok with that and can work around it. Everyday finish carpentry work, this has my approval
Glen M.
Dust collector arrived quickly and as promised. Works great and far superior to the stock version!
Wendell I.
Super easy install ! And works so much better then the stock one . Should have switched a long time ago !!
James D.
The screws were missing for the rubber flap, but otherwise the installation went well.
Michael W.
I was a little disappointed in the 3d print quality. There were a lot of loose plastic strands inside that will most likely buildup with dust. Otherwise the item fit my equipment as expected. Haven’t had a chance to evaluate the dust collection performance yet.
Bernard P.
Great product, could be less expensive.
Mike W.
Make a better housing. Mine broke the first time I used it. I cut a scrap 2x4 to see if the collector actually picked up any dust. Sent these same photos to Shop Nation who responded with a 50% discount on replacement parts.said my damage was from kickback and proceeded to give me advice on how to use my saw. I’ve been using miter saws for 30 years. I did not take the discount.
Rodney W.
works great
Charles M.
Missing small parts, 6 mm socket head screws
William G.
Quick and easy to install. Went from basically no dust being collected to catching most of it. Its not perfect, but for a miter saw it's as good as you can get and pretty inexpensive.
Carole W.
I had my Dewalt all set up with a baby sunshade for the beach. Seemed the cheapest and it worked great for sawdust control.
Then, I saw this item of yours, I bought, installed, and am happier than a day to the wood store!
It works great, I have a dedicated shop vac, I throw that power, fire up the saw, get er done and that's that....no sawdust!!
LOVE IT!!!

I’m tired of explaining the poor assistance I received. I was passed off to four different people over a hour: the original contact, a parts person who nothing about parts for my Dewalt, then to a “work order” person, then to billing? I really got tired of the whole process, and it seemed like a scam, so when asked to enter my credit card info, I hung up and called the FCC and the Better Business Bureau.
Douglas K.
It definitely reduced the amount of sawdust not being collected from the DeWalt collection system. I would say it is collecting around 80 to 85% of the sawdust.
Justin S.
It works well. If you're considering buying this i recommend it. In my opinion it's an elegant solution to an obscene problem.
pete g.
exelent!!
Kent B.
The dust collector works as advertised. When I watched the video on YouTube about the process of developing this collector it sold me on it. You have to keep in mind he said it collect around 85% and that is a good estimate.
Robert T.
100% better than the factory collector. Only draw back is the flexible rubber piece…used the saw/dust collector a few dozen times and the rubber piece already has a few cuts in it.
Maria N.
Easy to install... 100% effective attachment.
Shane B.
Works great, let’s me move my Dewalt 779 miter saw closer to the wall, and the installation was super easy thanks to the QR code to the video that comes with it. Great product, very happy with it, my only complaint is that I didn’t buy it sooner!
Jacob C.
My dust collection system went from picking up 25% of the dust to 80%. Love it!
David F.
The dust chute fills up with dust after about two cuts. It is worse than the stock Dewalt chute.
