The Fortress A Hitch Lock fits the Knott Avonride hitch found on Ifor Williams Trailers and Ifor Williams horse boxes. The AK351 found on many Brian James Trailers over 3.5 tonne trailers will also fit this hitch lock. Fort A will also fit Alko AK350 Cast Head, Alko AK3500, and the Winterhoff WW200 Cast head. For confirmation for which model hitch fits this hitch lock or other hitch locks, please refer to our hitch lock selection fitting guide.
