A really simple wheel chock....

[TXiceman]

Here is what I use on both sides of my trailer. Made from a couple of pieces of 4 x 4, a couple of eye bolts, a couple of washers and four nuts. And the clamp force is provided by a couple of mini-chain boomers.

I made mine very similar, but used all-thread in place of the boomer and eye bolts. Yours appears much more convenient to use. Aaah, yet another project for my list.

I had made a set with the all-thread rod, but you had to get a wrench out to tighten it. With this set up, once you get the eye bolt lengths set, just snap up the boomers. Since there is a slight difference in wheel spacing...be sure and mark them right and left.

That's using the old noggin!

Well done indeed.

TXiceman,
That is a very well thought out and beautifully executed invention.
When "doomsday" comes, I hope I am parked somewhere in your vicinity!
