This Trailer Hitch Lock device will go a long way towards preventing your boat trailer, caravan or box trailer from any “un-authorised” towing.
The robust, non-corroding casting will fit most popular couplings.
You fit it inside the coupling, remove the barrel lock and key, insert the Allen key (supplied) and turn it, which expands the diameter of the casting, securing it in place.
Re-insert the barrel lock and use the key to lock it in place.
The casting cannot be removed without your key.
The device comes complete with an Allen key, barrel keys and a convenient container to store it in when not being used.
Suitable for most 50mm ball couplings.
