As the name implies a Slam Lock automatically locks and secures as the door is closed, requiring the use of the correct 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 locks fitted to your vehicle load doors, to genuine slam operation. The slam lock replaces the manufacturer's vulnerable barrel and internal mechanism where appropriate, with high security products, designed to resist attack and tampering.
