Abstract: For a preset having a cover and an annular ring supporting the cover, structure to releasably hold the cover in closed position and to move the cover with respect to the ring as between closed and open positions, the structure including a deforming surface on the ring; a deformable head on the cover to engage the surface, the engagement causing the deformable head to deform and generate friction forces sufficient to hold the same against said surface means for holding the cover in closed position but permitting the deformable head to slide relative to the surface means to provide for the cover to be moved out of or into the closed position; an elongated lifting tab on the cover; and the lifting tab being pivotally mounted for movement between an inactive condition and an active condition, in the latter condition part of the tab extending inwardly of the cover and part of the tab extending outwardly of the cover to be grasped by the fingers for moving the cover from closed to open position.

Abstract: An electrical junction box particularly suitable for fabrication from molded plastic has a generally rectangular horizontal cross-section with a flat bottom wall, a pair of oppositely positioned flat side walls substantially parallel to each other, and a pair of end walls which are positioned opposite each other in a substantially parallel relationship, and which run between the edges of the side walls. A pair of hollow post members having a U-shaped lateral cross-section extend upwardly from opposite edges of the bottom wall along the opposite inner surfaces of the end walls. Each of these hollow post members has a bridge structure for supporting a fastener extending across the top thereof, this bridge structure having an aperture formed in its center for permitting the passage of an attachment screw.
