Fortress K Hitchlock (FORTK)


The SAS Fortress hitchlock range is a versatile range of high security hitch locks that can be fitted either when unhitched or hitched to your trailer or caravan.

SKU: 2160761 / 2160762


Insurance approved hitchlock completely covers hitch head and bolts.

The Fortress K hitchlock fits Albe cast head, Knott braked pressed head and Knott unbraked pressed head, may require removal of stand, as well as the Winterhoff WW8, WW13 & WW30 cast hitch. For unbraked trailers with the hitch to fit this hitchlock, the total height from the top to the bottom of the fixing bolt can be no more than 73mm to fit, due to the way the hitch is mounted on the drawbar. If the bolts on the hitch are too long, they can be ground down to fit as necessary.

This hitchlock fits on some Ifor Williams trailers and other unbraked trailers, where the maximum height of the hitch, including bolts and drawbar is 73mm. The bolts can be trimmed down to suit, as long as there is a couple of threads exposed from the nut. For confirmation for which model hitch fits this hitchlock, please refer to our hitch lock selection fitting guide.

This hitchlock will fit hitched and unhitched to towing vehicle, to prevent your car and trailer being separated in a car park or motorway service station.

The maximum-security safe style lock on this hitchlock has twin hardened pins to lock and anti-drill protection on the lock to deter thieves.

The hitchlock finished in zinc pacifate and painted bright red for maximum visual deterrent.

Compact and easily stored, which makes it ideal for touring. A tough plastic hitchlock carry case is available from SAS at an extra cost.

Other hitchlocks also available for other hitches.
