The UNI-VAC is the ultimate shop vacuum accessory. The super flexible rubber grips around most sizes and shapes of vacuum ports. Adapts to most table saws, routers, miter saws, sanders, and the list goes on! The innovative locking teeth allow you to secure the UNI-VAC in place. The fixed end attaches around all vacuum hoses with an inner diameter (ID) of 2-1/4” such as RIGID® Hose. Another great innovation, designed by a cabinet maker!
