RACO 8233 – Frequently Asked Questions
1) Will the RACO 8233 4 in. square box work for conduit runs with 1 in. EMT?
Yes. The 8233 comes factory-punched with eight 1 in. knockouts, plus two 3/4 in. and two 1/2 in., so a 1 in. conduit run terminates without drilling. It's built specifically for conduit wiring systems, not cable.
2) How do I mount the RACO 8233 square box? Does it have a bracket?
No bracket. The 8233 ships as a bare welded box, so it is supported by the conduit entering it or fastened through the box itself. If you need a box that nails or screws to a stud face, order a bracketed version instead.
3) What's the difference between a welded box and a drawn box, and which is the RACO 8233?
The 8233 is welded. A welded box is formed from sheet and seam-welded, which allows the deeper 2-1/8 in. body and more knockout positions; a drawn box is pressed from one piece with no seams and is typically shallower with fewer entries. For conduit work with multiple terminations, welded is the usual choice.
4) Does the RACO 8233 come with a cover or a plaster ring?
The box body only. A 4 in. square box needs a separate flat blank cover, a device cover, or a raised plaster ring to suit the device and wall finish, and those are ordered separately. Any standard 4 in. square cover or ring fits the box.
5) Can I use the RACO 8233 as a pull box for a conduit run that changes direction?
That's one of its intended uses. The 2-1/8 in. depth and twelve total knockouts in three trade sizes give you room to land multiple conduits and pull conductors through at a junction or directional change in a raceway system.
6) What is the manufacturer part number for the RACO 4 in. square 2-1/8 in. deep welded box?
RACO 8233. That's the number to quote for the 4 in. square, 2-1/8 in. deep welded steel box with no bracket.
