Schaller S-Locks are a professional strap locking system designed to keep your guitar securely attached at all times. The system replaces your standard strap buttons with hardened steel locking buttons and uses an adjustable strap holder to fit different strap thicknesses. A patented Lock-Wheel with triple security prevents accidental release, even during aggressive playing. An extended thread supports straps up to 6mm thick, while the stainless steel locking bolt reduces wear and increases long-term reliability. The redesigned pull-up ball gives clear tactile feedback so you know when the lock is fully engaged. The Lock-Wheel can be tightened securely by hand without tools, or tightened further using a 2mm Allen key. S-Locks are engineered for silent operation with no rattle, making them ideal for stage and studio use. Medium size dimensions: Male thread: 4.0mm Inside diameter: 3.0mm Length: 22mm A simple, secure solution for keeping your guitar safe while you play.
