Vestil LWC-15 Laminated Rubber Wheel Chock, Overall W x L x H (in.) 10-1/4 x 5-1/2 x 11

I work on diesel trucks and these are perfect. They are heavy and built solid.

These are great, got me out of a jam while I was pulling a junky old Dry Van and had to slide the seized tandems to be legal, without these the tires were just skidding behind me. A+

I received these from amazon.ca today. One was in a torn up box, and the other was not in a box at all. They were both rusty (covered my hands in rust handling them) and dirty and the bolts holding them together were cut on an angle and razor sharp (dangerously). I have a feeling that these were pre-used. At over $50 each, this is NOT what I expected to receive. I will have to re-paint them and use a power tool to clean up the sharp bolt edges. I do not recommend these to anyone else. Be very careful handling these if you do buy them.

Solid and well built. Did the job.

These chocks are heavy and have substantial dimensions. I use them for a double axle enclosed freight trailer but they could be used in any application for vehicles, RVs, boats and trailers in which the user needs an ability to insure stability for storage, jacking and loading and unloading. The surfaces have a high friction potential and don't slip. There a solid welded handles for helping to place and pull the chocks which can be tied off with cording for more ease of access. This is a first rate product, more expensive than cheap, smallish plastic units commonly available but superior in every way they should be. Highly recommended!
