Schaller S-Locks S Strap Locks - Nickel

With Schaller Security Locks, Schaller developed and patented a completely new product in 1981, probably the most secure connection between guitar and strap. In 2018, the next generation was introduced with the S-Locks.

S-Locks: S for Safe, Silent & Schaller strap locks
In the development of the new revolutionary S-Locks we have combined 3 parts to perfection:

- unique one-piece hardened steel strap buttons
- S-Locks suitable for different belt thickness with ergonomic operation
- and a patented locking nut - Lock-Wheel - with triple security architecture.

The S-Locks new strap button
- new and unique one-piece construction, easy to install via 3 mm (1/8") Allen key.
- special 3.5 mm wood thread in S-Lock size S for maximum grip. Optionally available in sizes M (4.0 mm) and L (4.5 mm). Please refer to the installation instructions in the description below for size specifications.
- hardest steel for maximum wear resistance and safety
- including high-grade felt washers to protect your instrument

The S-Locks improved new lock
- extended thread length for holding straps of up to 6 mm thickness,
- newly designed slanted locking bolt made of stainless steel for minimum wear and thus maximum safety
- new design pull-up ball for best haptics
- suitable for a standard hole in the belt of 10 mm

The new Lock-Wheel: featuring 3-stage safety concept
- Lock-Wheel with special patent thread ensures a secure hold. It can be tightened safely by hand without tools.
- The 2-hole mount (suitable for 2 mm Allen key or screwdriver) allows a firmer tightening torque of the Lock-Wheel with maximum hold.
- Undetachable hold due to grub screw with tapered cap and slot 2.5 x 5 mm made of stainless steel. Simply unscrew the set screw again to unscrew the Lock-Wheel; the thread remains functional and cuts itself "free" again through the Lock-Wheel.
