In 1981, Schaller developed and got the patent for a totally new category of product, which revolutionized the connection between guitar and strap. With its unique design and functionality, Schaller has been setting the standard in strap locks for decades.

In 2018, Schaller paves the way for the next generation of revolutionary strap locks. Schaller proudly presents: The new S-Locks, S for save, S for silent and S for Schaller strap locks.

These new revolutionary S-Locks are silent. They feature one-piece hardened steel strap buttons, aesthetic design, perfect handling, an elegant Lock-Wheel and all former hiccups have been tackled. 3 pieces = 1 S-Lock - perfect.
