The Schaller S-Lock Security Locks. The original just got better! Ingenious design, superb materials and outstanding quality.

For decades the most popular strap lock system for guitar and bass. They protect your instrument by preventing accidental release of strap. Includes high-grade felt washers for ultimate protection of the guitar's finish.

What's new?

  • The overall design has been improved
  • End-pin and screw now one part rather than two
  • Sprung lock mechanism improved for easier usage.
  • Improved strap locking ring

Schaller Security Locks can be used on acoustic guitars as well. Screw Security Lock pin into tail-block and heel. Avoid screwing into the unreinforced part of the sides.

  • Michael Smith


    The ultimate in guitar strap retention. So easy to remove and connect but solid during use. GAK provides brilliant service.

  • James


    Great strap locks!

  • Brian


    Super high quality and very smart looking. Too early to tell how long they will last but they have an excellent track record.
