I needed an easy way to mount and carry spare tires (one for a truck and one for a trailer). These E-Track mounts worked great when paired with single E-Track sockets. In this case, I wanted to place them in the back of my truck. It was as simple as adding two sockets to the side of the bed and fitting spare tires. My only suggestion is to add wing nuts for easy hand tightening. I went to my local hardware store but they didn't have wing nuts of that size or thread (which was metric).
