Vacuum adaptor
I have a great Bosh shop vac but their hose is very small. I needed this to make it work with some of my power equipment like my planer ans my horizontal sander. With out adding my vac they can clog up so this was a necessity!

2.5 to 1.25 dust hose adapter
Adapters are what they are. These seem to work ok, A built in gasket of some type for the ends would be useful, current use really thin foam craft sheets cut to needed size.

David H on Nov 5, 2016
Saw the company on Wood Whisperer YouTube video. I needed an adapter that would fit small table top equipment. When I Google searched and found what I needed was with Rockler, I chose to open an account and ordered the part. The information on the website also helped by giving ID and OD for each end of the adapters.
Chris S on Oct 14, 2016
I use a lot of dust collection adapter's, it is always good to have them around when a new tool is purchased. Rockler has the best selection of all.

Les J on Nov 8, 2015
I chose this product because I am in the process of putting together a Dust Removal System in my woodworking shop. It has been my experience that Rockler stocks good reliable components for that task. I chose to buy from Rockler because they go out of their way to help me when I need advice. They have been my "Go To Supplier" for the last seven years. I can always depend on their products to be of the highest quality, just like their customer service.

Will this fit on dewalt miter saw that has a 1 1/4" OD outlet?
Sal B on Sep 25, 2015
BEST ANSWER: This one would have the same size 1-1/4" OD as the outlet you have. Item #42248 has a larger end of 2-1/2" OD and a smaller end of 1-1/4" ID so it would fit into the 1-1/4" OD that you have.
will this adapter connect DIRECTLY to a standard shop-vac hose? (or is this a M-M issue that needs a F-F coupler??)
New User U on Jul 28, 2015
BEST ANSWER: Yes it will. I use this on a small counter top belt sander and my shop vac hose fits inside the adapter (2 1/2" end) .
Will this fit a Makita 2705 table saw?
