The Chock-N-Lock is an easy-to-use device, designed to chock, lock and stabilize your dual axle RV or trailer. Used to help eliminate front-to-back rocking motions and securing of tandem tires to prevent movement while parked or re-hitching, the Chock-N-Lock stabilizes the suspension and eliminates the sway and movement commonly associated with dual axle trailers. Made using the latest in injection-molding technology and patented design, the Chock-N-Lock is made from a heavily reinforced plastic composite that is lightweight, yet strong and durable. With a simple turn of a wheel, the revolutionary ergonomic turning mechanism of the Chock-N-Lock allows for easy fitment by all ages without causing hand strain. Unlike similar products which require crawling underneath the trailer to fit, the Chock-N-Lock can easily and safely be installed from either a standing, kneeling or comfortable seated position, tested up to ten (10) tonnes holding weight. Because wheel spacing can vary greatly between trailers, the inclusion of two (2) sets of Chock-N-Lock extension plates* allows for compatibility with wider wheel spacings and eliminates the need to purchase, install, and continually adjust pairs of stabilizers. Packaged for wheel span between 3-15/16inch to 9-1/2inches. Backed by a three (3) year manufactures warranty, the Chock-N-Lock can be fitted both vertically or horizontally depending on the size and profile of your tires and for added security, has an integrated locking cap to secure a padlock (padlock not included). *Additional extension plates can be purchased separately.
