The X-Chock starts off where the Deluxe Tire Locking Chock left off but its new, slimmer design will fit into more axle applications. Provides added stabilization and prevents tire shifts by applying opposing force to tandem tire applications. As opposed to other chocks, the X-Chock works with the tires' natural movement instead of against them. Fits even the tightest of applications retracting down to 1-3/8" and extends to 12". Rust inhibitive coating. Plated ratchet wrench with comfort bumper included. Lightweight, easy to store. Lockable for added security with optional 28015 Pad Lock.2 Pack. Made in the USA!
