Half Mortise Chest Lock with Key - Steel 2-5/8" x 1-9/16" | BM-6546

Half Mortise Chest Lock with Key - Steel

Secure your antique chest, trunk, or cabinet with this half mortise chest lock (BM-6546). Unlike a surface-mount lock, a half mortise lock is partially recessed into the wood — the body is routed or carved into the lid or door, leaving only the back plate, top edge, and latch plate visible once installed. The result is a clean, period-correct look that sits flush with the surface.

Sold individually with mounting hardware and key included.

About Half Mortise Locks

Half mortise locks are a traditional furniture locking mechanism used on chests, trunks, blanket boxes, and cabinets throughout the 18th, 19th, and early 20th centuries. The half mortise design — where the lock body is partially set into the wood — provides a more refined appearance than a fully surface-mounted lock while requiring less routing depth than a full mortise lock. They remain the preferred choice for authentic period restoration work.
