A multi-point closure control mechanism or lock especially designed for use with rear and/or side doors of a closed body highway truck, particularly a so-called panel truck, and for use with doors of military vehicles. The closure control mechanism comprises two dead bolts, slidably supported in suitable brackets adjacent to the upper and lower edges of a door near its free vertical edge, that engage keepers or catches in the form of plates on the vehicle body. Each bolt has a free running roller therein to facilitate entrance and retraction of the bolt into and out of engagement with its respective keeper or catch. The dead bolts are connected by rod members to pivots eccentrically located on a lock operating member rotatable in a frame member fixed to the door intermediate the bolts. The operating member also includes a cylindrical rod-like projection extending normal to the free edge of the door when the bolts are engaged with their keepers or catches at the top and bottom of the door. The rod-like projection has a roller to facilitate its engagement with and release from a keeper or catch. One embodiment of the aperture member has a mechanism for selectively disabling an outside handle connected to the mechanism.
