This Fisher CL JV 5 man T-Pad sled is ideal for middle school through high school programs because of its TITE-LOCK modular chassis that provides the rigidity needed in a multi-unit sled. Player safety is improved due to the wraparound design of the T Pads.The main frame is tough, durable and guaranteed to last for 5 years. The all metal surfaces are powder coated to prevent rust and the leaf spring design virtually eliminates all spring cracking and breaking. The 30 degree angle on the skids assures you of a smooth transition over your field without chewing up your turf or grass. The high density, 100lb impact resistant foam is covered with durable 18oz vinyl covers that are then double and triple stitched to withstand harsh weather and years of hard use.
