Schaller S Strap Locks S for Safe, Silent & Schaller

In the development of the new revolutionary S-Locks Schaller has 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 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 guide above.
• hardest steel for maximum wear resistance and safety 
• including high-grade felt washers to protect your instrument

The S-Locks improved 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 improved S-Locks-Wheel: featuring 3-stage safety concept -

1. 1) Lock-Wheel with special patent thread ensures a secure hold. It can be tightened safely by hand without tools.
3. 2) The 2-hole mount (suitable for 2 mm Allen key or screwdriver) allows a firmer tightening torque of the Lock-Wheel with maximum hold.
   • Use the Allen key or a thin screwdriver to tighten the lock wheel completely before screwing in the micro screw to secure it.
   • This gives the lock a firm hold, the 3 conical pins on the inside of the lock penetrate the leather strap and prevent the lock from twisting.
   • Straps made of leather, imitation leather, fabric and other materials have the property that they adapt under pressure over time, which is why the lock wheel should be tightened regularly.
5. 3) Undetachable hold due to grub screw with tapered cap and slot M2.5 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.
