JUNCTION BOX FOR INTERCONNECTING ELECTRICAL CONDUIT ABSTRACT AN enclosure consisting of a wall, which is open at one end, containing tubular projections perpendicular to the wall and an outward flange and seal at the other end forming a base, whereby the junction box can be secured to a concrete form, prior to the concrete being poured, for a wall or floor or ceiling. The other end of the wall of the junction box is sealed by means of a fitted lid which is held secure to the box by means of two screws. Each tubular projection, being dimensioned internally to receive an end of an electrical conduit, contains a "Knock-out portion at the end forming a portion of the wall of the box, which seals the opening of the tubular projection at the wall of the box. This "Knock-Out" portion when removed creates a ring on the interior of the tubular projection, which is wedge shaped, forming a locking device permitting an electrical to be inserted into the tubular projection, and having been inserted cannot be withdrawn. There are locations on the interior of the box at which interconnecting grounding wires and fixtures can be adhered to. The lid, which seals the open of the box, has a lip, which fits within the interior of the walls of the box. This lip is wedge shaped at the edges and engages the conduit when the lid is placed on the box in such a manner that further restricts the conduit from being withdrawn.
