A rim lock (Dutch: kelderbandslot) is a simple surface-mounted lock screwed onto the inside of a door. The Dutch name refers to its base material: the lock case is formed from strip steel. It is operated with an old-fashioned long key.
How it works
A rim lock is surface-mounted: it is not let into the door but screwed on top like a small box, which makes it easy to fit:
- A single deadbolt — with the long key you throw the bolt out or in to lock it.
- Left- and right-handed — the lock works on both left- and right-opening doors.
- Galvanised — the steel is usually galvanised so it does not rust quickly outdoors.
Application
- Shed and store doors
- Garden gates and doors
- Cellar and cabinet doors
Especially where no heavy burglar-resistant lock is needed, but a simple, robust means of locking is.
Points to watch
- A rim lock provides basic security; for a house entrance or high burglary requirements a certified (multi-point) lock is better.
- Fit the lock on the inside so it cannot be dismantled from outside.
- Versions with a cylinder are also available, so a standard key can be used.
