A cargo bar equipped with an adjustable mechanism for limiting the force that can be exerted by a ratchet that serves to secure the cargo bar in place extending between opposing surfaces of a truck body. The ratchet mechanism extends one of the two in-line bars of the cargo bar. The other bar is carried on a plunger. A compression spring is located between the plunger and ratchet housing to compress when the ratchet handle is reciprocated to wedge the cargo bar in place. A stop moves with the plunger to a position where the stop interferes with actuation of the ratchet handle when the spring has been compressed to an extent coincident with the desired maximum force. The stop is adjustable to vary the force limitation.
