ABSTRACT:
A chalk line reel includes an opening in the housing that permits access to a powdered chalk storage area. A movable door is mounted on the housing, and the door is movable to a closed position in which the door obstructs the opening. A first element on the door releasably couples the chalk line clip to the door, and a second element on the housing releasably couples the chalk line clip to the housing. The first and second elements are positioned such that clip resists movement of the door away from the closed position when the clip is coupled to the first and second elements.
