Our Trampoline Rocket Track is 6 feet wide and 18 inches high. The frame pads are designed so that there is no way to slide into the springs or under the frame! The Rocket Track is available in lengths from 4 to 60 feet! We also make an in-ground version. Prices of the Rocket Track are $124 per foot for the above ground model (sold in 4-foot sections) and $104 per foot for the in-ground model, excluding tax and shipping.
