A slamlock is a device that automatically locks the vehicle door immediately it is shut, without requiring any operation by the driver.
It is primarily designed for applications such as multi drop delivery, high value loads and applications where the owner/ operator requires control over the security of their goods. It is the function that appeals as much as the security.

Another major advantage with mechanical slamlocks is total control. Electronic systems often have either global (all doors) or area (load or cab) unlocking- this leaves the unrequired doors vulnerable until the auto relock action operates. Slamlocks do not have this vulnerability.

L4V slamlocks integrate with the vehicle manufacturers’ locking systems. This provides Maximum Security along with straightforward installation. They combine a genuine Security Slam operation with a high visual deterrent and a pleasing appearance.
