A hand crank cam lock for connecting medium to large sized display walls or boards including a hand crank disposed in a cam lock. The hand crank cam lock is configured to join two separate extrusions or frames together in a toolless manner. The hand crank cam lock locks these frames when the hand crank is turned clockwise, a plurality of hooks slide back along channels inside an outer body to grab the inner walls of a frame. This will in turn lock the hooks into place against the inner walls. The hand crank will only require half a turn to travel the required distance to lock the hooks into place and this half turn may be performed via a tool or by hand.
