As the name implies a Van slamlock automatically locks and secures as the door is closed, requiring the use of the legitimate key to regain access. Due to the automatic operation of a slam lock they are recommended for load area doors and are Ideal for multi-drop situations. Upgrade and convert the standard vehicle (O.E.) locks fitted to vehicle load doors, to genuine slam operation. The L4V kit replaces the manufacturer’s vulnerable barrel, and internal mechanism where appropriate, with High Security custom designed products, designed to resist attack and tampering. We do not endorse the practice of ‘upgrading’ the O.E. lock to slam operation by the addition of springs, this method offers no additional protection to the door and cannot be considered a security upgrade by itself. Due to Health and Safety issues, Construction and Use Regulations and security issues; Locks 4 Vans do not, as Company policy, supply mechanical slamlocks for cab doors. For this application we recommend an electronic product.
