These economical fittings will help you build a high performance dust extraction system for your shop. Made of ABS plastic (except for the aluminum blast gates), these fittings are designed to stand up against the abrasive nature of saw dust and wood fiber. Universal Tool Adapter adapts your wet/dry vacuum hose to stationary or portable power tools. It's constructed of a tough material and conforms to slight variations in size. The "stepped" design contains a 1", 1-1/4", 1-1/2" and 2" external diameter and a 1-1/4", 1-1/2" and 2-1/2" internal diameter connection. It also has a square flange with mounting holes that can be used with a collection box. Because of the danger of static electricity involved with dust collection we highly recommend the book Dust Collection Basics #85O17 to be read prior to any installation.

    Very disappointed

    This part looks very, very nice. Sadly, it does not fit a SawStop dust port. The 4" side is the exact same size as the saw's dust port. Tomorrow I shall be returning the part.

    Absolutely worthless

    This is absolutely worthless. I have 2 new machines with 3 4" dust ports. This product will not fit in the dust ports, it is exactly the same size the dust port. Therefore, it CANNOT be a reducer as advertized. Now I have to waste my time shipping it back.

    I will buy more of these.

    This connects my 4" sanding pickup, for my wood lathe, to my 2.5" dust pickup system.
