I needed a clamp to hold the fireplace door handle which was dangling and dangling in the door. I removed the handle from the door, placed the drill stop on the end of the handle, and reattached the handle to the door. After getting the handle in the right position, I tightened the set screw. Valla! No more dangling grip. It may not be exactly the application it was designed for, but it worked brilliantly for the purpose I needed.
