A latch holds a door closed and releases with a handle. A lock adds a key, thumbturn or other mechanism that prevents the door from opening.

MacBlair stocks door locking and closing hardware for repairs, replacement work and new door installations. The range covers simple sliding bolts, concealed fittings and latch mechanisms for doors that need to close securely without a key.
