X Chocks Wheel Stabilizer for Travel Trailers PRO [Specially Designed for Travel Trailers] Camper Wheel Chock Scissor Anti-Move Tire RV Accessories and Parts Multi-Function Wrench

Chocking an RV, or any trailer is important, and these devices handle the chore easily. After they've been installed once, very little adjustment is needed to uninstall, and then reinstall - or - if space is essential, they can be fully collapsed. When they aren't fully collapsed, installation is only 30 seconds per side. Once installed, the wheels aren't turning - period. The plastic covered handle is also a nice touch to hold the device in place while synching the adjuster tight.I had the misfortune of experiencing a serpentine belt failure on my tow rig, forcing a tow. Even though I had to pull over and park on a decline, with these chocks in place, the RV didn't even shift when it was unhooked, and placed on the jack-stand. The situation would have been much dicier using regular wheel chocks.Getting the chocks into the engagement range does take some turns using the provided wrench. You'll need the wrench as there is too much resistance to use just fingers. If you lose the wrench, the adjuster wheel is 19 mm, which is a pretty common size, or you could just use a crescent wrench. Also, make sure the wheels are close enough to be within the range of adjustment for these chocks. Their spec says up to 10 inches...

These wheel chocks/stabilizers are worth the money and time to use them. My camper feels more sturdy when moving about inside and the peace of mind knowing it's not going anywhere is a plus as well.It takes a minute or two to put them between the wheels but well worth the time. I would buy them again.

Thought I would only need these in difficult terrain or slopes. Had purchased them and didn't even use for a while. But I saw a YouTube video of someone mentioning it cutting down on shaking of the camper when moving around inside. So I used it on our last tramping trip and it made a huge difference! It keeps the tires from slightly moving back and forth as you walk around inside. It made the whole camper feel so much more sturdy. And you can't beat the safety of these as chocks.

Once you put this on and tighten it down, your trailer isn't going anywhere! Not only does it do a fantastic job as a chock, it stabilizes your trailer a little more as well. Other reviewers have complained about the wrench that comes with it, but I've never had a problem with it. I kept the box it came in (sturdy cardboard and foam-lined) to allow for easy storage. Accessing the tightening nut in the center is much more convenient for me on our trailer since it would be very difficult to reach with the traditional X-style chock (on top). BUT... my only gripe with the nut being in the center is I can't use my drill. The nut has to be tightened one... turn... at... a... time. I know... first world problems. I tried doing some research on what size ratcheting open-end wrench to purchase but found conflicting sizes. So see the in picture attached for the size I measured on mine using a crescent wrench with a width measurement on it. Looks like 1 1/16". A ratcheting open-end wrench will make quick work of opening and closing the chock. Otherwise, it's fantastic!

We had these set up quickly with the nut to expand located in the middle of the unit. Much better design than the ones that expand with the nut on top of the units. The box it came in is so nice that we decided to keep it stored in it. The box has study foam cutouts and a built in handle. Really satisfied with the quality and operation.

Seem to be sturdy and well made. I will see over time how long they last in weather. Will keep an eye for rust to start. Wish they would of used some kind of rubber coating or something for the elements.

When I compared chocks like this at first I had trouble making sense out of the rubber coating turns out it’s a very ergonomic handle for positioning. Now I’m glad I bought them they’re just right hold tight easy to position, fast to set and built strong.

Just using them the first time this week. The are very well built and sturdy. They extend to lock into place with less turns than I expected. So far they work great. They keep my toy hauler from moving at all when walking around inside, Recommend for sure
