Abstract
Low-height reversible ratchet tie-down winch for flat decked vehicles. The tie-down winches are adjustably mounted in retainer channels extending along each side of the deck of the vehicle. Each winch is rotatably mounted between the top and bottom walls of its base and tension of the tie-down chain is maintained by a pawl and ratchet. The winch block has a chain pocket to lock a horizontal link of the chain to the chain pocket and a recessed portion engaging a next adjacent vertical link of the chain. The ratchet has a cooperating pocket engageable with a next adjacent vertical link of the chain and completing the chain pocket in the winch block. The chain may be trained through one end or the other of the base for the winch.
