Proprietary design fits all versions of the Andersen Ultimate 5th Wheel connection to include both funnel applications (steel and red poly) and the new upgraded eye bolts.  3/16 welded steel construction with a no-nonsense design which encompasses the Andersen Ultimate 5th Wheel adapter protecting all connection bolts and set screws while still accommodating the release cable and the eye bolts of the safety chains (if so equipped).  Accepts most “puck” style locks (sold separately) which by design are completely bolt cutter proof. Time, noise, power tools or a cutting torch will be required to defeat our lock design which will eliminate most theft interest.  We also sell a few different brands of the “puck” style locks (sold separately) with varying levels of security. DO call us for clarification if you have any questions. We offer discounts starting at 10 or more Ft. Knox Locks.  Bright yellow powder coat. Made in America!
