The box has a base for mounting on a surface and a cover secured to the base by screws. A pair of tabs are disposed close to the base end of the cover and each tab captivates a screw. Assembly of cover to base is simplified because the cover can be held in one hand while a screw driver in the other hand turns the screws. Inventory is reduced because a single length of screw is employed irrespective of box depth.
