Schaller S-Locks Sizes

(Schaller GmbH accepts no responsibility or liability for the correctness, accuracy and completeness of the technical drawings shown.)

Please read the S-Locks user guide before selecting or installing S-Locks from our store.

Important: 

• We recommend choosing the strap button first to match the size of the existing hole in the guitar.
• If the hole is too big or too small, please choose a different strap button or reduce, close, re-drill or extend the hole.
• If necessary, countersink separately in the area of the outer lacquer layer to prevent the lacquer from flaking off when screwing in the strap button.
• Carefully screw in the strap button into the wood and, if it is too tight, unscrew it again and gradually drill up the drill hole.
• If the strap button is too easy to screw in, then reduce or close the hole and drill again appropriately.
• Tighten the strap button "hand-tight" to the instrument body. Do not continue by force. The wood may break, flake off the paint and tear off the strap button.
• Please check the secure fit of the strap button in the wood regularly and retighten the screw if necessary or reduce or close an enlarged hole as described and re-drill.

Compatibility between Schaller old Security Locks and current S-Locks

a.) S-Locks are compatible with all existing Schaller Security Locks like this: 

• strap button old SecLock + lock new S-Lock (without silent feature!) 
• strap button new S-Lock + lock old SecLock only limited, we do not recommend it.

→ Please always use our new S-Lock lock with Lock-Wheel on your strap, then you will always be compatible with all strap buttons and at the same time you will always use all the advantages of our new Lock-Wheel.

→ Please always make sure that the lock is engaged in the strap button, the lock is attached to the belt in such a way that the strap button is secured in the U-shape of the lock and that the instrument does not rotate.

b.) One strap for several instruments 

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).

How 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.
