The new AL-KO Lockable Coupling range incorporates a lock into the body forging of the coupling for a built-in anti-theft solution. This eliminates the need for a separate coupling lock for simple, convenient & cost-effective protection.

The locking solution offers protection whether the trailer or caravan is connected to a towing vehicle or when left parked.
When in the lock position, the coupling simply restricts necessary movements of internal components required to engage or dis-engage the tow ball from the coupling.

The couplings are compatible with a standard 50mm tow ball and match existing popular hole patterns for an easy swap over for retro fitment. Each coupling comes with 2 keys.

The added feature to this range is the new XL Grip handle – providing an enlarged grip area when compared to the classic coupling design for enhanced comfort and ease of use.

An AL-KO mechanical Overide Coupling is the ideal solution for trailers with a laden mass up to 2000kg. At the time of writing, braking systems that use an override principal meet legal requirements, as long as they provide adequate braking for the trailer and tow vehicle combination.

The principal of this type of coupling is a sliding shaft attached to the tow ball housing of the coupling. As the tow vehicle slows down the force of deceleration is passed through the coupling shaft and pushed either on a mechanical linkage (for mechanical brakes) or on a linkage connected to a hydraulic cylinder providing hydraulic pressure to a braking system (hydraulic brakes).

This type of coupling is most efficient if the ball load is not excessive and when load levelling devices are not used, as these devices impede the smooth operation of the coupling, ultimately impeding the braking performance.

When reversing, the attached collar would be fitted to prevent inadvertant brake application. The collar should be removed from the shaft during normal towing use.

For Hydraulic brake applications, this coupling would be fitted with the AL-KO Hydraulic brake conversion kit (AL-KO Part Number 610941).

For mechnical brake applications, this coupling would be fitted with the AL-KO Mechanical Override Brake Plate (AL-KO Part Number 614051).
