Factory chute vs. Shop Nation
See the difference
Factory dust chutes leave a gap right where the blade throws the most debris. Ours is engineered around the DeWalt DWS779/780 Sliding Miter Saw to close it and steer chips into your hose, so they stop ending up on the floor, the fence and in your lungs.

FAQ
Questions, answered
Which saws does it fit?
It's made specifically for the DeWalt DWS779/780 Sliding Miter Saw. Match the model number on your saw's label before ordering.
Do I need a vacuum or dust collector?
Yes. The chute steers debris into your hose, so you'll need a shop vac or dust collector connected to it to get the full benefit.
How hard is it to install?
It's straightforward. It bolts into the same spot as the factory chute, with no cutting, drilling or modification to your saw. Most installs take a few minutes.
Can I go back to the factory chute?
Yes. Nothing on your saw is modified, so you can put the stock chute back on any time.
How much of a difference does it really make?
A big one. The chute closes the gap where factory chutes let the most debris escape, so far more chips end up in your vac instead of on the floor, the fence and in the air. Read what 3,552 woodworkers say in the reviews above.
Phenomenal dust collector, but it just exploded from a small cut off hitting it. For $50, and a rather complicated installation, I would expect it to last longer.
Holy crap! This sucker is freaking awesome! I have actual dust collection on my saw for the first time. DeWalt is foolish for not paying you to sell this as a standard feature.
There are some limitations with cutting angles, which is to be expected with a saw capable of compound, miters, etc., But overall installation was easy and cutting is virtually dust free. Thanks for making such a great product!
Assembly to the dewalt saw was a little more complicated than I thought it would be.
The dust collection is attached to a 6hp shop vac. After test cutting a couple of pieces I’m not sure if the new chute is working much better. However, I’m willing to give it a try.
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.
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.
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.
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.
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.
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!
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
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.
Though the dust collection is improved, cutting 1 x 6 baseboard vertically shredded the flexible rubber shroud and yanked it so hard that it ripped the screws out of the 3d printed piece.
I suppose I would have been more careful had I been warned
Works as advertised! I had to take my saw blade off to get the exiting dust collector chute off, no big deal. The new Shop Nation dust collection chute installed without a hitch. After the first time using the saw with the new dust collection, I saw a significant reduction in wood particles on the floor.
I believe the original design does not provide a deep enough slot for the rubber insert to seat securely. As shown in the attached pictures, the rubber continues to come off after approximately every 10 cuts. I have cleaned the slot thoroughly each time with a jeweler’s screwdriver and blown it out with compressed air, but the issue persists. This appears to be a design or fitment problem rather than a maintenance issue, and I would like it addressed. A practical solution would be to revise the design by making the slot deeper or adding a more secure retention feature so the rubber insert stays properly seated during use.
Install was really easy following the instructions. I have the DeWalt DWS709 which they say should be compatible on the website. And it was. Very pleased with my upgrade so far.
So far so good. I only knocked off a star because of the hose. I didnt ask nor look hard enough, but none of the hose adapters included work with the Dewalt hose system. I guess i thought this went without saying. But I had to fenagel a transition using what was provided with cutting, taping and using leftovers I had laying around so as to not go out and buy more stuff. That is the photo attached. However, this DOES do a much better job collecting the dust than the stock version.
Good idea, bad execution. I was cutting off half an inch from my piece and the excess flung up and hit the 3D printed piece. It chipped the plastic and at the same time caused the flap to get cut up by the saw blade. I only used it a couple of times, so value wise I down grade it. I would wait til they cast it out of metal.
Truth—Miter saws—mine is the 780–have terrible dust collection. True—this modification is a marginal improvement; see photo. True—the 3-d printed piece is flimsy; part of mine broke when it dropped it during installation, and not from great height. True—installation was far from as depicted. To remove the lower blade guard, I had to remove the blade (which is a pain), pry apart the lower blade guard assembly to get to the Torx fitting. Thankfully, it kind of works, since my lower blade guard is in pieces. You should be upfront about this; your installation video is more than a little misleading.
This is an update to my 4 star review I let earlier right after getting the product and using it for a few days. It has been a few months now and the same problem keeps happening, small pieces get pulled up and getting stuck, then block the chute, and its like you have nothing on there at all. Then mine cracked this last time of removing the debris. I suggest staying away until they open the chute or find a way to keep the small cut offs from getting stuck.
Durability. Not even used for 6 months. Wood chips come off a miter saw. It’s what they do. They need to be able to hold up. My OEM lasted well over 10 years before it wore out.
You only back your product for 45 days. That tells me you doubt your durability as well. Not sure I’m a shop nation customer any longer.
It dramatically improves dust collection on my Dewalt 780 . But don’t do what I did . I have a miter saw sled with a 4 inch fence and made a cut at a 45 and I cut into the plastic chute 😂😂😂😂
It was a little difficult putting on cause I didn’t know what I was doing, but once I got started, it all came together. If I could give it a rating of 1000 I think I would. The product is a little light and I’m not sure how long it’s gonna last but right now it’s fantastic and I’m sure that I don’t use it very much. It will last me a lifetime. I don’t build furniture, but I use this saw half a dozen times a year and it’s in my basement so I like it clean. I don’t like it dusty and believe me this product takes that dust away and that’s what makes me wanna rate it 1000%.
