pic: Delta field at River Rage - Side Rail detail

Detail shot, the diagonal brace is hinged and separates at the mid-point to make the side rails flat pack better. The pre-punched angle is bolted to the rail frames and base plates. Base plates look to be 0.375" hardwood flooring painted gray. Velcro on the bottom to lock it to the carpet. These side rails took a few good hits from robots and seemed to take the abuse pretty well.
