ConstructionReducer - It's made with heavy walled ABS plastic construction made for durability and to withstand the wear & tear commonly associated with woodworking dust collection.

  • Works well
Size: 2.5" x 4"
It’s definitely fit the collector and reduces it easily, installation was easy connection is tight. I think it’s a good value for what it does. The rubber is very durable and quality. It should last a long time.

  • Precise Fit for DXV05S-QT When Upgraded to a 2 1/2" Hose
Size: 2.5" x 4"
Very well made, precise fit that is also lightweight. Very useful silicone flexible adaptor with clamps as well. I used it to vacuum out a clogged dryer vent and it was beautifully compatible with my upgraded 2 1/2" hose fitted on my Dewalt Stealthsonic DXV05S-QT. The connectivity is effortless. It is a very worthwhile addition to the attachment kit I put together for handling various cleaning up situations. ... show more

  • Works fine, good value
Size: 2.5" x 4"
Purchased to adapt 4" dust outlet on bandsaw to a 2-1/2" hose on a wet/dry vacuum. Fits fine and solves the problem. Not wild about the screw clamps. It's nearly impossible to use a nut driver on them, and the way the heads are cut a Philips bit doesn't work well, best to use a flat head screwdriver. Wish they had the clamps with sort of a wingnut-shaped mechanism to tighten and loosen them, would be much easier to install. ... show more

  • Used for my contractor table saw dust collection
Size: 2.5" x 4"
Perfect fit on the Woodstock Table Saw Flange (available on Amazon) to make a sawdust collector for my old Delta contractor saw. The output opening is also a perfect for the standard 2.5 in shop vac hose.
