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. The new S-Locks. S for safe, S for silent and S for Schaller strap locks! Strap button New and unique solid one-piece strap button in hardened steel with self-tapping wood thread. Simply screw it on with an Allen key (size 3 mm). 4 mm/ 5/32“ screw with self-tapping wood thread. Fits all existing strap buttons incl. Gibson for perfect replacement without adjustments on existing holes and screws. Hardened steel and more than double thickness of the strap button guarantees maximum security against breakage.
