These Camco wheel chocks are exactly what we needed for our trailer setup. They’re made of heavy-duty plastic but are still lightweight, making them easy to carry and position. The built-in rope is a small but smart feature—it makes pulling them out from under the tires quick and convenient without getting your hands dirty or reaching under the wheel. They hold the trailer securely in place, even on slight inclines, and give us peace of mind when unhitching or parking. They’re a perfect fit for wheels up to 26” and have held up well through several uses. For the price, quality, and function, this 2-pack is a great deal. Highly recommend for any RV or camper setup.

Great Wheel Chocks

Style: w/ Rope Design, Size: Pack of 2

Does the job. Before I unhitch my small trailer I put one in front of one trailer wheel and one behind the other. If you have ever had a trailer rock back or forward after disconnecting, you know how scarry that can be. Small, light but sturdy, and reasonably priced. Does the job.
