Concealed-Door Box Lock, 72 x 57 x 15 mm

Plan a discreet closure for a compatible concealed or access door. This compact steel box lock fits a suitable prepared door arrangement without the bulk of a large external lock body.

✅ Keep the mechanism compact - The small box format suits a matching door cavity.

✅ Use it in a concealed-door project - Its form is intended for compatible hidden and access-door arrangements.

✅ Plan from defined dimensions - The 72 x 57 x 15 mm size helps compare the available fitting space.

Check the Door Mechanism Before Cutting

Compare the lock body and operating arrangement with the door and frame design. Concealed and sliding doors can have different alignment requirements, so match the actual mechanism rather than the door style alone.

The painted-steel lock is supplied as one unit. Plan suitable fixing hardware and any required strike arrangement as part of the complete installation.
