Schaller S-Locks (Security Locks)

Schaller's new S-Locks feature one-piece hardened steel strap buttons and an unique Lock-Wheel with 3-step locking system. Also they are fully compatible with all existing Schaller Security Locks and with Rockinger Lock Pins!
The solid strap button features a 4 mm/ 5/32“ screw with self-tapping wood thread and is easy to install. Simply mount it with an Allen key (size 3 mm). Fits all existing strap buttons incl. Gibson for perfect replacement without adjustments on existing holes and screws. Felt washers are included.
The Lock Wheel with patented self-locking thread can be turned on it by hand. If you think that's not safe enough take a 2 mm or 5/64’’ Allen key or screwdriver to tighten it for maximum security. You may also attach it permanently with the set screw.
