SAS Fortress A Knott Avonride Hitch Lock
SAS Fortress A Hitch lock for Knott Avonride Couplings
High-security Towing Hitch Lock for Knott Head is usually fitted on most Ifor Williams Trailers, Plant trailers, Horsebox trailers, standard trailers and many other single and twin axle trailers.
The SAS Security Fortress A Hitch Lock fits on the Knott Avonride hitch. Ifor Williams Trailers and Ifor Williams horseboxes are both fitted with Knott Avonride Hitches. The Alko AK351 found on some 3.5-tonne Brian James Trailers will also fit this hitch lock. Other Hitches that Fort A will fit are:
Alko AK350 Cast Head, Alko AK3500, and the Winterhoff WW200 Cast head
The AK351 looks similar in appearance to the Alko AK301 hitch lock which fits the SAS Fortress B
The Fort A will fit your trailer hitch whilst hitched or unhitched to your towing vehicle. This prevents your car park or motorway service station thieves from separating your car and trailer because the hitch handle will be covered.
