Link 4001 One & Both Side Key RIM Lock

A Link 4001 One & Both Side Key RIM Lock, also known as a surface-mounted rim lock or box lock, is a type of door lock that is installed on the surface of the door rather than being mortised into the edge of the door. Rim locks are commonly used on wooden doors and are typically found on interior doors, such as bedroom doors or bathroom doors, although they can also be used on exterior doors in some cases. Here are some key features and characteristics of door rim locks:

Surface-Mounted Installation: Door rim locks are installed on the surface of the door, typically on the side facing the interior of the room. This makes them relatively easy to install compared to mortise locks, which require a recessed pocket to be cut into the edge of the door.

Components: A typical door rim lock consists of a lock body, a latch bolt, a strike plate, and a key-operated cylinder or thumbturn mechanism. The lock body is mounted on the surface of the door, while the latch bolt extends into the door jamb or strike plate to secure the door when closed.

Latch Operation: The latch bolt is operated by turning a key in the cylinder or by rotating a thumbturn mechanism located on the interior side of the door. When the door is closed, the latch bolt automatically extends into the strike plate, holding the door securely closed. To open the door from the outside, a key is inserted into the cylinder and turned to retract the latch bolt.

Keyed and Keyless Options: Door rim locks are available in both keyed and keyless configurations. Keyed rim locks require a key to operate the lock from the outside, while keyless rim locks feature a thumbturn or push-button mechanism on the interior side of the door for easy operation without a key.
Overall, door rim locks are a convenient and practical option for securing interior doors in residential and commercial settings. Their surface-mounted design, ease of installation, and simple operation make them a popular choice for homeowners, landlords, and property managers looking for an effective and affordable door locking solution.
