The BAL FASTJACK Full-Timer Tripod King Pin Stabilizer is the Big Brother to the original TriPod FASTJACK. The lightweight yet sturdy, hybrid design is made from aluminum and steel with a rust inhibitive finish. It slips onto the trailer's pin and uses gravity to assist in setup. A pad lock is included to lock it to the trailer's pin. The independently adjustable legs use a unique ratchet system. Large base pads offer increased stability. It collapses to a compact size to help with storage.
