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.

    "I would buy this product again and agai

    Unlike the previous reviewer , I guess I just knew that the measurements given are for the hose sizes that you connect to the "adapter". It's not a "go between" for other hard fittings , unless there are female ends on them. I am presently using three of these adapters on different machines with NO problems at all,and will buy more as needed.

    This makes no sense!

    I fail to see how they can sell these items without letting you know if the ends are male or female. Based upon simple measurements, I thought I was getting what I needed. Instead I have a 2 1/4" male which will not hook up to the male end of my shopvac hose ... and a 4" male end that will not hook up to the 4" male end on my piece of equipment. This thing is of absolutely NO USE to me at all.
