Realistic fulcrum pivoting action conditions your players to achieve leveraged power over an opponent without losing their balance. The only sled that is completely adjustable. Adjust spring tension, pad height and angle. Each individual blocking unit is made up of "pigs" and pads. The "pig" is constructed with a high strength 1/4" steel plate, double welded for maximum strength and durability. The "pig" attaches to the steel chassis and is fully adjustable. Exclusive spring tension adjustment is an integral part of each "pig". The pad fits onto the "pig" and is fully adjustable.
