The Saracen Ultra is constructed using Fullstop Security’s special blend of composite metals which have been specially chosen to be resistant to cutting, drilling and gas freezing. The Saracen Ultra was designed in Purple Line’s UK innovation centre. It is designed specifically to fit AL-KO hitches, and is therefore a perfect fit around the hitch, where some generic hitch locks may leave a lot of space around the hitch, causing rattling, and leaving them far less secure and vulnerable to crowbar attacks. The Saracen Ultra is suitable for AL-KO AK130, AK160, AKS1300, AKS2004 & AKS3004 caravan and trailer hitches.The Saracen Ultra comes complete with a free carry case, security hitch ball and lock protector.
