Abstract
A chalk reel has a housing defining a chalk chamber and an opening for accessing the chamber. A door is movable between an open position for allowing access through the opening to the chalk chamber and a closed position preventing access to the chamber. A lock assembly is provided on the door and is movable with the door. The lock assembly rotates relative to the door between a locked position and an unlocked position and reciprocates to secure and release a lock member.
