Dunlop Strap Lock Washer

This is a set of washers that takes up the space in your Jim Dunlop Gutiar/Bass strap locks when your strap gets stretched out. Makes the middle strap hole.550" instead of .370". This takes up some of the space in the strap hole so it doesn't work it's way over the strap lock.
Make with raft and support. Drill out center to 3/8" if needed. The raised side goes under the button cap.
