(SOLD)RotoChoks! They don't make 'em any more. $50 pair.
These are absolutely the finest wheel chocks I've ever seen. They were manufactured by a small shop in Delaware until a few years ago when they ceased production. Too bad, because the design, materials, and machining are of the highest quality. I no longer have my TT nor need for these innovative chocks.
$50 for the pair plus shipping.
