Upgrade your RV stability with the X-tended Fit X-Chock Wheel Stabilizer-engineered with heavy-duty, rust-inhibitive zinc-coated steel. Specially built for dual axle trailers with wide-stance tire spacing, this model extends up to 17 in. at the foot pads, making it ideal for larger gaps between tandem wheels. The X-Chock stabilizes your trailer by applying opposing force between tires, minimizing unwanted movement while working with the tires' natural motion-not against it. Perfect for travel trailers, 5th wheels, and RVs, the package includes two X-tended Fit X-Chocks, a 3/4 in. ratchet wrench with comfort bumper, and supports an optional lock (28015 Pad Lock) for added security. Enjoy worry-free setup backed by a limited lifetime warranty and a more stable camping experience wherever you go.
