The AL-KO coupling lock fits directly to standard 50mm ball couplings preventing a ball from being inserted in to the coupling until it has been removed. The AL-KO coupling lock is powder coated and zinc plated components for corrosion resistance.
This new locking system is designed to secure your trailers, caravan, horsefloats, marine trailers or any towed vehicle that is fitted with a standard braked or unbraked 50mm ball coupling.
The unique design means that this unit is an all in one device, requiring no additional padlocks or locking device, as the locking device is built in. The AL-KO Universal Coupling lock has three keys as part of the kit, so you should not get caught if you misplace your keys.
The AL-KO Universal Coupling Lock is designed so you can park your towed vehicle, detach you car or 4WD and have peace of mind knowing that your trailer or van will still be there when you get back. Cheap copies are like leaving your trailer unlocked so please be aware.
