The AL-KO Security is designed to fit the AKS 1300/ 2004/ 3004 Stabiliser/ AK160 or AK 300 coupling heads and also the AKS 2000/ 2500/ 2700 Stabiliser. It is made of high grade special steel, with a red powder coat finish to provide a robust and attractive design. The AL-KO Security Device covers the coupling handle. This prevents the coupling handle being lifted, so the caravan/trailer cannot be coupled to unauthorised vehicles and towed away.
