Rim Locks

Rim locks are relatively easy to install and can be a cost-effective option for securing a door, such as bathroom doors. They are available in a variety of styles, including traditional, antique, and modern designs. Some rim locks also have the option for a deadbolt, which provides an additional layer of security.
Rim Locks (54)
A rim lock, also known as a surface-mounted lock, is a type of door lock that is installed on the surface of a door, rather than in the door itself. Rim locks are typically used on interior doors and are often found in older homes. They consist of a latch mechanism that is mounted on the inside of the door, and a keyed lock with a handle that is mounted on the outside of the door.

One of the main benefits of using a rim lock is that it does not require the door to be drilled, which can be a major advantage for older homes or for those who want to preserve the integrity of their doors. Additionally, rim locks are often less expensive than other types of locks, making them a popular choice for budget-conscious consumers.


However, rim locks also have some limitations. They are typically not as secure as other types of locks and may not provide enough security for external doors or for homes in high-crime areas. It is also recommended that you use additional locking methods like using a deadbolt to enhance the security.

Rim Lock FAQs

What is a Rim Lock?

A rim lock is a surface-mounted lock fitted to the inside face of a door. Unlike mortice locks, rim locks are fixed to the door’s surface rather than being recessed into it.

Where are rim locks commonly used?

Rim locks are often used on internal doors, garden gates, sheds, and period properties. They’re particularly popular for rustic or traditional interiors due to their vintage appearance.

Are rim locks secure enough for external doors?

While rim locks provide a basic level of security, they’re generally best suited for internal doors or low-risk external doors such as gates or sheds. For front doors, a mortice lock or BS3621-rated night latch is usually recommended.

Can I use a rim lock on a bathroom door?

Yes, rim locks with built-in privacy snibs or separate thumbturns can be used for bathroom doors. Make sure the lock offers privacy without needing a key from the inside.

Do rim locks work with standard door handles?

Rim locks usually require a rim knob set, which is designed to work with the surface-mounted mechanism. These are available in matching styles and finishes for a cohesive look.
