The Avonride Head on Ifor Williams Trailers was specially in mind with the design of the the Fortress A hitch lock for Ifor Williams Trailers. The SAS Hitch Lock gives maximum security by completely covers the hitch head and bolts and makes it insurance approved.

Fits:

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. Please note that the AK351 is very similar in appearance the the AL-KO AK301 hitch lock which fits the SAS Fortress B. Please check for the writing on the hitch for the model number to ensure you are choosing the correct hitch.

This lock fits the Debon 500, 500XL and 700!

The Fort A will fit to your trailer hitch whilst hitched or unhitched to your towing vehicle. This prevents your car park or motorway service station thieves separating your car and trailer because the hitch handle will be covered.
