ABSTRACT:
In a dunnage jack bar assembly of the longitudinal ratchet type wherein the length of the jack bar assembly is adjusted by a carriage slidably mounted upon the jack bar having locking and power pawls operated by an oscillating operating lever wherein the pawls engage the teeth of the jack bar to translate the carriage thereon. A quick release lever mounted upon the operating lever selectively lifts the locking pawl from the jack bar teeth to permit a rapid translation of the carriage on the jack bar in either direction.
