Yep, drilled PVC. Don't make the holes too close or it will fold under the weight on a hard roll. The protector is attached with about 5 zip ties drilled through the roof. The bigger the better as I wanted "black" ties and only had little ones and on a hard roll doing the dirt mount jumps I broke it off, and damaged the Blubeam antenna and the mount connector on the IRC transmitter. It was repairable, but a pain, and a weak point is not using the stronger larger zip ties.
