I needed something to keep my trikes from rolling into my exhaust on my truck, as well as some security when on my trailer. I started playing around with the tig and this is what I came out with.Here is a shot of the bottom side . Works great I used two hood pin's to mount it, so it could be put in almost anything, two 3/8 dia holes are all that is needed. Just drive into it and lock the cable, no need for straps I can change it out from my trailer to my truck in about 30 seconds, the cable is adjustable and i used marine aluminum so it should last about 200 years. Notice the 3ww window sticker, thanks again x owner!
