From the manufacturer: The X-Chock 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 10”. Rust inhibitive coating. Plated ratchet wrench with comfort bumper included. Lightweight, easy to store. Lockable for added security with optional 28015 Pad Lock.
Made in the USA!
My experience: I bought a set of two X-chocks on Amazon for $54.48. We have a 2017 2185 and we were loosing sleep at night when my son would move around in his top bunk or climb down the ladder. We noticed a huge difference with the X-chocks in place. The trailer seems a lot more stable and we sleep soundly now. THESE DO NOT REPLACE STANDARD CHOCKS. THESE WORK IN ADDITION TO STANDARD WHEEL CHOCKS.
For those considering buying one X-chock vs two X-chocks, I did an experiment with only one X-chock in and although it made a difference in helping with trailer movement, it was much better in reducing movement with both installed.
