Abstract: A case for holding and carrying plumbing connections, tools and the like when closed has two opposed hinged doors covering one face of the case, the free edges of which doors meet midway between the opposed hinges. A handle held centrally above the open face of the case when the doors are opened and secured to the box allows the use of the open case as an open work tray. Brackets attached to the inside faces of the doors provide a resting place for a second case thus allowing stacking of the cases for a parts bin to be used at a job site.
