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

These are easy to install and work great!

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!

A little Expensive for the Quality. Work descent.

Sulythw X Chock, RV Wheel Chocks Stabilizer for Travel Trailers.This is a very heavy duty and solid piece (2) of equipment. Once you put these on your trailer it is NOT MOVING. We have a 22 foot Arctic Fox trailer that is great for us as it has no slides and is not too big for two. We can go pretty much anywhere. This chock is actually too big for us.It works well but it must be tightened from a nut in the middle. Each chock comes with a wrench and has a built in handle so you can hold the chock in place while you tighten it. When I use them I only loosen them enough to remove them and insert them the next time. I do not make them as narrow as possible as when they were new. I have purchased a second slightly smaller set of chocks like these that work in the same manner.If you have a larger rig like 30 feet or more I would highly recommend these chocks. They are as described and very much worth every penny for a larger trailer or fifth wheel or even a motor home.

They are sturdy and definitely helped against rocking. The wrench is awful, it bent first time out and the adjustment design doesn't work with a normal wrench. Will have to make some modifications to them for ease of use.

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.

Edit: A company rep reached out to me about my experience. They wanted to make it right and I feel they did. Because of this excellent customer service, and the high quality of the new chocks (link below), I am adding 2 stars. I don't mind when a product needs improvement as long as the company acknowledges the issue and tries to correct it. These guys did that and I am grateful. I am now using a newer product from them and it has the built-in wrench (so you never have to look for one, and they came with two combination locks to deter theft. They seem Very, well built. Time will teel of course. If they fail, I will edit once again. But for now all is well.New units: https://www.amazon.com/dp/B08M5C6PH4/ref=sspa_dk_detail_6?psc=1&pd_rd_i=B08M5C6PH4&pd_rd_w=EX1rw&pf_rd_p=0c758152-61cd-452f-97a6-17f070f654b8&pd_rd_wg=udmHn&pf_rd_r=05RKE9QHADZK8NF0P8KY&pd_rd_r=d36174c1-1efa-4420-84f3-b9a23ce9c46b&s=automotive&smid=A1WSTF44CN7YLC&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyNk9OTU9WQ0c2MkVMJmVuY3J5cHRlZElkPUEwNDE3NTkyRVhPS0hCQ0RNV1owJmVuY3J5cHRlZEFkSWQ9QTA2NzY5NDgzT1NUQ0s2TlJUN1hPJndpZGdldE5hbWU9c3BfZGV0YWlsJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==Original review: So my X-chocks finally got so old they needed replacement. I noticed these and thought why not try them. FIRST time I installed one, the following happened: As soon as the unit just began to firm up, the included wrench, bent. I'm talking about less torque than when you install a spark plug (basically finger tight). The jaws of the flat thin wrench (big surprise) bent open. So I found a 1 1/8" open-end wrench (lucky I had one and it's not 1" like the description said) and immediately realized using my own wrench will not work. You might get a single small turn but then you can't get the wrench off, so you have to loosen it to where you started. Flip the wrench over and same thing. So I decided to pull the unit out to the very edge of my trailer tire so there would be more room to swing the tool. Still not going to work. Sure, it was 12% better, but now it would take me 100% more time to install and UN-install these, not to mention that they would now be on the very edge of my tires and not safely in the middle of the tread. They seem built well (except for the paper thin wrench) but in actual use, they fail design-wise. I am now looking at similar units with the 'handle' already incorporated.

Great gadget to help the trailer from rocking when walking inside

Don't wait until your tip out breaks.

Great value and product, sI wish I bought them years ago.

Easy to use,great handle. A product that camper owner should have.

The picture shows 2 chocks and in the write up it says 1 "Set". In my books that would mean you get 2. I would never have bought it if it was only one as all the rest have 2.
