  • Works well
Style: 4" to 2-1/2" Reducer & 4" Cuff, 1 Set
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.

  • Well made and fills a need. Support your local maker.
Style: 4" to 2-1/2" Reducer & 4" Cuff, 1 Set
Well made for a basement 3D printed item. Works fine. Fair price. Filled a need perfectly, and I appreciate the ability to support other makers. Need: I do amateur digital electronics and solder at a bench in a home office a lot. I built a custom exhaust fan / vent setup using a home "grow" fan and shop vac 2.5" ducting. The fan and exhaust are 4". I exhaust everything out the window through a dryer fitting and baffle. The 2.5 ducting gives me velocity and 4" gives me the volume. It works well under my microscope / soldering stage. ... show more

  • Precise Fit for DXV05S-QT When Upgraded to a 2 1/2" Hose
Style: 4" to 2-1/2" Reducer & 4" Cuff, 1 Set
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
