ABSTRACT:
An improved enclosure for electrical use comprising a box having an open top and front, and a cover for closing both openings simultaneously. The front is bordered by lips turned inward from the sides, and near its lower end is provided with a pair of internal ramps sloping downwardly backward. The inside surface of the front portion of the cover, near its bottom, carries a rod whose ends extend into engagement with the ramps when the cover is placed on the box. The top and side edges of the cover are formed with resilient rims to engage the outer surfaces of the back and sides of the box, and are formed from the material of the cover itself by a multiple successive right angle bends in the same direction. Means are carried by the top and the back for preventing removal of the cover, and include apertured lugs for a padlock, a screw having a pentagonal drive recess, and means for preventing lateral access to the periphery of the screw. The enclosure is to be mounted by anchor bolts passing through lugs at its bottom.
