Bulldog AJ10 Hitch Lock

Tax included

Suitable for use on Alko hitch heads including the latest 3004 model, the AJ10 has been designed to be strong, easily handled and resistant to the most determined attacks. It can be used whilst the caravan is stored or attached to the vehicle and incorporates a unique design that allows the stabiliser handle to be completely lowered, enabling the stabiliser function of the hitch head to be used whilst towing. A feature not found on some other hitch locks.

Fitting the Bulldog AJ10 is simplicity itself, just place the laser profiled steel hood over the handle of the hitch and lock it in place with the 25mm diameter Sold Secure approved lock bolt. For increased security the lock is positioned under the hitch head to safeguard against any attempt to lever the hitch lock off.

The Bulldog AJ10 comes with a steel ball for when the caravan is not hitched to the tow vehicle.
