2 Pack Heavy Duty Large Solid Rubber Wheel Chock with Handle for Travel Trailer, Truck, Commercial Vehicle and RV, 10" x 6" x 7.3"

First of all, these things are built like a brick. You could run over them and never damage them. They are a bit heavy, but again, they are tough. You could use these for a semi truck. Our very large horse trailer is going no where which these chocks on the wheels. They are made of solid rubber, with a handle on the end. No hole to put any rope handle on but plenty of room to make one. They smell like new rubber out of the box but its nothing strong or offensive as some others suggest. The reflective striping is just adhesive tape and there is no telling how long it will last. The important thing is it does its job as a wheel chock, the striping is not important to me. They have a long taper on the end that fits well under the tire to prevent it popping out when the wheel rolls back against it. This could also make them difficult to remove if they have any weight on them but at least they wont be popping out. I highly recommend this product!

I have a 22' center console that is on a trailer parked on a slight grade running from the house toward the street. I worried that winds could shift the trailer causing it to roll down into the road. It is because of this that I purchased these chocks. They are a hard resin inside and covered with thick rubber outside that keeps wheels fixed in place. The bottoms are ridged to provide a strong footing. Since getting them, the boat has been in winds over 40 MPH and the trailer didn't budge. I highly recommend them.

Stink like no tomorrow. Leave them outside in the yard for a week or so before storing them in a closed area. They will stink up an entire garage. Excellent weight, sturdy, bigger than I thought, good value.We bought these for our camper and were exactly what we wanted (that's why I mentioned the stink, don't put them in dry storage until they cure out. Your camper will stink for a long time.).

After our plastic wheel cock blew out of the truck, I found these HD rubber ones to replace. While they weigh a few pounds, they are incredibly durable and functional. 3 years running and I’ve bought them for other family members I camp with as well!

The chemicals this thing must have in its composition is not something to ever bring into the house. It made us nauseated just because we opened in our home. We quickly took them outside and use them with an older pickup truck that is a stick shift just in case the parking break isn't enough or should it pop out of low range on a hill.Works great - highly recommended - store outside always

These worked very well, I used them to chalk my front wheels on my 12000 lb RV, I had to jack up the rear pretty high and I was on a little down hill as well, ( sketchy ) But the chalks held the RV no prob. Sat like that for 2 days, It was the only thing holding it from rolling. Pretty good. Chad.

Using this with a full-size bus, mostly in a garage. The rubber chock itself is solid and even when it deforms under the weight of the bus it seems quite sturdy. Even on a smooth concrete garage floor the chock doesn't move, assuming you give it a shove under the tire. It will slide a little if you are planning on just driving onto it without placing it by hand. I'm sure on rough concrete it would hold even better.The reflective tape looks nice but is cheap and barely adhered to the chock – the tape on the sides started peeling immediately, and the first line completely fell off complete within a month.Others said they smelled bad at first, and I agree with that, but the smell dissipated almost entirely within a couple days of use. I'd still store them in an outside compartment on the vehicle if possible.

There are a lot of cheap, plastic chocks out there. If you really want something that will work and last, these are the one's to buy. They will smell so when you get them, put them outside to off gas but no doubt, they will work.

I like the combination of black and high visibility yellow. Good quality nice handle on the backside.This is a quality product.
