Earlier I stated that the clamp has slots and brackets to affix other pieces. The kit includes three hook-like devices.
The hooks are easy to snap in place and are just as easy to remove if you wanted it in a higher or lower set of holes.
To make the hooks more versatile, a large rack called the Track is also included in the kit. The track attaches to the clamp via the brackets. The track provides many more places for the hooks to clip into.
