Extra buttons for your Schaller S-Lock strap lock system. Now you can use one S-Lock equipped strap on multiple guitars.
The button and screw are now one piece, keeping them as quiet as possible. The threads are slightly wider than other strap button screws, which is nice for strap button screw holes that are stripped or have been enlarged slightly over time. These require a 3mm Allen wrench for installation.
Set of 2 with felt washers.
