Stanley Staple Gun Helper/Wire Holder

This small piece was immensely helpful in stapling wires with one hand, without putting a staple through one of them!

This staple gun has a built in wire holder, but it is offset from the staple a bit, so the cable can bend right into the way of a staple very easily. This was created to eliminate that. It may fit similar models as well.
