ABSTRACT:
The invention comprises an electrical junction access device such as a junction box or a cover member therefor for positioning in a wall structure. The device includes a main body defining an opening and having outer surfaces facing away from the opening. The device further comprises guide means disposed outwardly of the main body and defining guide surfaces generally opposed to and spaced from the outer surfaces of the main body. A junction box according to the invention may also comprise port means in the front-to-rear walls with knock-out tongues disposed thereacross. The tongues have rear edges adjacent to but spaced from the back wall of the box whereby such edges may be engaged from the exterior of the box. Frangible connecting elements connect the tongues to the box distal the rear edges of the tongues.
