King Pin Tripod FastJack is the lightest king pin stabilizer on the market, offering full adjustability on each of the three legs. The TriPod FASTJACK slips on to the trailer's king pin to help support the FASTJACK and uses gravity to assist in setup. No need to worry about uneven ground while setting up as each leg will independently adjust to the ground using the integrated ratchet system. Apply tension as needed and enjoy maximum stabilization. No assembly required, it is ready to use straight out of the box and will easily collapse to a compact size, making it simple to store. The large base pads help give you a firm footing. Adjustable from 40 to 60 inches. Weighs only 19lbs. Rust inhibitive finish. Lockable to trailer pin with included pad lock. Limited 1 Year Warranty.
