Schaller S-Locks - protect your love

With Schaller Security Locks, we 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.

Concept and features

1 set S-locks complete with strap button S (3.5 x 18 mm) 

(see product description below for detailed assembly instructions)

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.

Final

• Put all parts together and give it a shake
• Sounds of silence - You will be amazed: Whether on stage or in the studio, S-Locks do not rattle.
