Question: Does this fit the D28115 Heavy Duty Grinder??
Document: I purchased this unit with a grinder and diamond wheel for grinding epoxy floor paint off. When I moved into the current house it had an epoxy coating on the floor the after a slight remodel doesn't work. I connected this to the Dewalt D28115 Heavy Duty 4 1/2inch / 5 inch grinder to remove the epoxy. It fit nicely and after an adjustment of the tension screw it fit securely. During use it directs almost all of the epoxy/concrete dust to the vacuum.
Seems like a good product, great quality, however it wont fit my ridgid grinder. Gave it to my co-worker who has a dewalt grinder.
I don't know about other brands, but the instructions say that even though it might fit other brands, it should only be used with DeWalt grinders. They have a quick-attach  shroud/guard mounting setup, and I could not get the shroud to stay tightened on my smaller and lighter Hitachi angle grinder.
I own a Dewalt DW400 4.5" angle grinder and I ordered this shroud thinking that it would fit on my Dewalt grinder. Not even close. There is no mention ANYWHERE in the description of this Dewalt product that it only works on specific Dewalt grinders. In fact, the Amazon add lists a Dewalt 4.5" grinder as being frequently purchased with this item, but it doesn't say that the shroud only fits certain grinders. Very poorly written description leading to much frustration.
It worked ok, but it should have had different hose connections. I have several shop vacs but none of them would fit the connection unless I went to the local HD and purchased one.
Ok, so you watch the video, and you think &#34;This is a video to get me to buy something. No way it works that well.&#34;  I was shocked and amazed that yes, it does work that well. Simply put, I was totally amazed. I wish it would have come with an adapter for the shop vac since it isn't nearly big enough to fit, but it is definitely worth every penny, especially if you're doing work indoors as I was.
Hooked it up to my Dewalt grinder, and shop vac, works great! It keeps the dust down when you need to grind the floor down. Thanks Dewalt !&iexcl;!
Used this shroud while grinding high spots down in out family room floor in prep for laminate flooring. Fits my Dewalt angle grinder exactly and allows zero dust to escape! Great product!
Used as shield during concrete grinding and the shop vac collected all the dust. Just duck taped a tapered attachment to the outlet and no dust. Just be prepared to empty the shop vac out a lot (again a sign it works). I used it on a dewalt grinder so not sure about other brands.
Most concrete dust was caught and vacuumed through the dust port. But when the grinder is tipped away from the surface a big cloud of dust escapes. Front gate openening is great for getting up against a wall. Wear a dust mask because there will be a lot of dust flying, but not so musch as using no shroud.
Answer: yes
