Schaller Button S-Lock L Black Strap Lock

Replacement Strap Buttons for Schaller S-Locks Size L

Schaller Buttons for S-Lock L Black are the official replacement strap buttons for the Schaller S-Locks strap lock system in size L. The set includes two one-piece hardened steel buttons measuring 4.5 x 27 mm, each paired with a high-grade felt washer to protect the instrument's finish. The 4.5 mm wood thread delivers maximum grip in the guitar or bass body, and the 12 mm standard diameter ensures full compatibility with all current S-Lock locks and legacy Schaller Security Locks.

Why Choose Size L

Size L is the longest of the three S-Lock button options (S = 18 mm, M = 22 mm, L = 27 mm), making it the right pick for instruments with thicker tops or deeper strap button holes. The black finish blends with black hardware, and the Silent Feature prevents rattle between the button and the lock during play.
