With Schaller Security Locks, we developed and patented a completely new product in 1981, probably the most secure connection between guitar and strap.

In contrast to our regular S-Lock range, where the strap pin and fastening screw are made of steel in one piece, the S-Lock Classic is the perforated strap pin sleeve, which is fastened via a separate fastening wood screw (not included in scope of delivery).

Both versions offer Schaller's proven quality for securely fastening the strap to instruments such as guitars or basses.

How Schaller S-Locks work

By pulling the ball with locking pin away from the lock, you release the safety catch of the Schaller S-Locks attached to the belt as shown in the illustration. The belt lock is released and can be pulled off the side of the button (pin) attached to the instrument.

• Schaller strap locks

In the development of the new revolutionary S-Locks we have combined 3 parts to perfection:

• unique 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.

Schaller S-Lock Classic set consisting of:

2 x S-Lock Classic strap buttons (without fastening screws)

• made of the hardest steel for maximum wear resistance and safety
• including high-quality felt washers to protect the instrument
• Dimensions strap buttons same as original security locks: Height: 10mm; Diameter outside: 12mm; 
  Diameter max. for screw head: 6.8mm; Diameter hole for screw: 3.8mm
• The strap button on the S-Locks comes in one size (12 mm in diameter): its dimensions do not vary across the three sizes—S, M, and L (with threads) and Classic (without thread).

Detailed assembly instructions can be found in our S-Locks guide an video (also in the tabs).

2 x Locks for S-Locks

• 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

2 x S-Lock-Wheels

• 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.
