Saracen Knott-Avonride is a high-security lock for caravans/trailers. Made with Fullstop Security's blend of composite metals that are resistant to cutting, drilling and gas freezing. The Saracen Knott-Avonride was designed in Purple Line's innovation centre in the UK. It is designed to fit Knott-Avonride trailers and is therefore a perfect fit for the towbar. Despite being designed specifically for Knott-Avonride towbars, the Saracen Knott-Avonride can also be used as a generic tow lock on a large number of other standard/pressed steel/cast trailer hitches up to 3500 kg. Installation includes placing the top half of the tow shield over the towbar and the lower half under the towbar before the high-security locking cylinder is passed through the shield and secures the Saracens. Saracen Knott-Avonride comes complete with a free bag, security ball and lock guard.
