Specifications: Overall Length: 150MM Overall Width: 90MM Minimum Door Frame Width Required: 14MM Black Caravan Frame Lock Motorhomes and caravans are usually fitted with one single lock, which can be easily opened. To help deter thieves additional locks are often required. Our lock helps to improve the overall security of your vehicle. It screws directly into the door frame of your vehicle, once installed the plate twists to partly cover the door, preventing it from being opened. To lock simply twist the plate over the door and push the lock in. When you're inside your vehicle the device can be twisted away from the door and locked, to stop anyone from locking it from the outside. Included are two keys, and all screws required for the easy installation.
