The Dust Shroud is designed for use with diamond cup wheels for floor grinding applications. The max. collar size is 1-13/16" which fits most 4" to 5" hand grinders including Makita, Bosch, and more. But it does not fit all grinders. Please check your collar size before buying.
The collar dimension of 1-13/16" is referred to the diameter of the hole on top where it would attach to your angle grinder. In most cases, the screw on dust shroud needs to be adjusted to tighten or loosen the collar before it can be used. Just loosen the lever and then adjust the screw and work it back into place. Once you get it in place, it will stay in place nor require re-tightening during your entire project.

Outside diameter of hose connector is 1-1/4". If it does not fit your shop vac, you can duct-tape them together.
