Mechanical Concealed-Door Box Lock with Keys

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.

Check the Door Mechanism Before Cutting

• ✅ 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 illustrated fitting diagram helps compare the lock body, bolt spacing and strike with the available space.

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 with the pictured keys and strike. Plan suitable fixing hardware as part of the complete installation.

One mechanical lock with the pictured keys, strike and trim pieces; door and fixing screws are not included.
