Ironton Double-Sided Rubber Pyramid Wheel Chock with Eye Bolt, 10in. x 5.5in. x 7in.

This is just what I was looking for, especially with the quality it was made with. I can use it between tandem axles on the trailer or in front or behind and wheel on any vehicle. It's heavy duty enough to do the job, and will probably last a long time, and easy enough to pick up with one hand thanks to the eyelit. I'll probably pick up one more my next time by the store. Hope they still have that one. I've purchased others somewhere else that have cracked or will not do what this one will. Real heavy duty, and does what it's made to do.
