ABSTRACT:
A door fastening apparatus, particularly well suited for fastening in closed positions the rear and side doors of truck bodies, includes an elongate tubular shaft rotatable to position a plurality of latch members in door locking engagement with a plurality of keeper members. A first latch member is rigidly permanently secured to the shaft near one end of the shaft. A second latch member is secured to the shaft near its opposite end by a bolted connection. The bolted connection permits the truck body manufacturer to cut the shaft to length depending on the height of the truck, whereafter the second latch member may be fastened in place without any need for welding. The second latch member is mounted on the outside of the shaft. A plug member is inserted into the sawed-off, open end of the tubular shaft. The second latch member and the plug member captivate the shaft wall. A bolt extends through aligned holes formed in the second latch member and in the shaft wall, and is threaded into a hole in the plug to form a rigid connection having an appearance substantially identical to a conventional welded connection.
