We have been selling ramps lately and have added a square rail to the inventory. The rail is 7ft long and stands 9" off the ground. The grind surface is a 2" x 2" square tube rail that will not dent from skateboarding. We also place a material on the bottom of the legs to give the rail traction to concrete surfaces. The rail can be purchased at Qskatepark.com and is pick-up only.
