Running conduit and need a junction point that handles two different pipe sizes without forcing an adapter mess or adding an extra box — this PVC round junction box gives you both 1/2-inch and 3/4-inch knockouts in a single gang, mounted depth. Injection-molded PVC body won't crack like metal boxes in damp locations. The 1/2-inch and 3/4-inch knockouts are pre-punched — you pop out what you need and the edge seats a locknut cleanly. Accepts standard single-gang device rings and covers. Suitable for exposed or concealed interior wiring applications. Standard in the truck stock of electricians and plumbing contractors across northeast Nebraska and northwest Iowa — the box that covers two pipe sizes without adapter fittings.
