The Schaller 446 S-Locks provide a secure, reliable connection between your guitar and strap while improving on Schaller's classic strap lock design. Built from hardened steel, the system combines durable one-piece strap buttons with an ergonomic locking mechanism designed for smooth, quiet operation. Schaller's Lock-Wheel uses a three-stage safety concept to keep the lock firmly attached to the strap, while the pull-up release makes removing the strap quick and easy when needed. Finished in chrome, S-Locks offer dependable protection for your instrument whether you're playing at home, in the studio, or on stage.
