Guardian Industrial Pallet Jack Truck Chock Rubber 11.5" x 11.75"

Works very well just a little light duty from what I have used on the past

A bit expensive for a hunk of rubber, but it does the job. My pallet jack no longer slides all over my truck damaging everything it hits. It will slide if you have to really get on the brakes or if they floor is oily, but other than that it stays put.

I had it only one week and it was already cracking , I'am a fright hualer so it gets a lot of use but won't hold up.
