RACO 8213 4 in. Welded Steel Square Junction Box with AC/MC/Flex Clamps

The RACO 8213 is a 4 in. square junction box built from welded steel for durable, code-compliant electrical rough-in work. This 1-1/2 in. deep box is equipped with integral AC/MC/Flex clamps for quick termination of armored cable, metal-clad cable, and flexible conduit, and it arrives with five 1/2 in. knockouts plus two 1/2 - 3/4 in. combination (TKO) knockouts for flexible raceway entry. The 8213 is UL Listed and ships with no mounting bracket, making it well suited for panel-mounted, bar-hanger, or surface installations where electricians need a rugged, dependable enclosure for splices, device mounting, or conduit transitions.

Key Features

  • Trade Size: 4 in. square footprint with a 1-1/2 in. deep body for standard box-fill applications.

  • Knockouts: Five 1/2 in. knockouts and two 1/2 - 3/4 in. combination (TKO) knockouts give installers multiple entry-point options on the same box.

RACO 8213 – Frequently Asked Questions

1) Do I need separate AC/MC cable connectors with the RACO 8213 4 in. square box?
No. The 8213 has integral clamps rated for armored cable, metal-clad cable, MCI-A and flex, so the cable terminates directly in the box without buying separate connectors. If you're pulling EMT or rigid instead, you'd use the knockouts with the appropriate fittings, since the built-in clamps are cable/flex clamps.
2) Does the RACO 8213 come with a mounting bracket, and how do I mount it?
It ships with no bracket. That makes it a box for bar hangers, direct stud or surface mounting, or panel mounting, where you fix it through the box itself. If you're nailing to the face of a stud at a set depth in new wood framing, order a bracketed 4 in. square instead, since this one gives you no bracket to set the setback.
3) Is a 1-1/2 in. deep 4 in. square box enough for my box fill?
The 8213 is a 4 in. square at 1-1/2 in. deep, which is the standard-depth 4S, not a deep box. It handles typical splices and single-device work. If you're stacking several MC cables plus a device and grounds, step up to a deeper 4 in. square, such as the Orbit 4SDB series welded steel deep box.
4) Can I use the RACO 8213 steel box outdoors or in a wet location?
The 8213 is a steel rough-in box with knockouts and cable clamps, not a sealed enclosure. For wet or washdown locations you want a gasketed or hinged-cover enclosure, like the Rittal 80181 JB series rated IP66/NEMA 4X, or a non-metallic screw-cover box such as the Carlon E987R in 6 x 6 x 4 in.
5) Can I use a PVC junction box in place of the RACO 8213?
Only where the wiring method allows it. The RACO 8213 is a welded steel box with integral clamps for armored cable, metal-clad cable, MCI-A and flexible conduit, which is a metallic system that relies on the steel box for bonding continuity. The Cantex E983G family is non-metallic PVC, so it suits nonmetallic raceway and cable systems instead. For AC/MC/Flex terminations, stay with the steel 8213.
6) What is the closest alternative to the RACO 8213 4 in. square box in the same 1-1/2 in. depth?
The Orbit D4SB series is a 1-1/2 in. deep 4 in. square junction box, matching the RACO 8213's 4 in. square footprint and 1.5 in. depth. The difference is construction and packaging: the 8213 is a welded steel body with integral AC/MC/Flex clamps, while the D4SB is drawn steel and is supplied in a pack of 100. If the terminations are armored or metal-clad cable and you want the clamps built in, the 8213 covers that without separate connectors.
7) Is the RACO 8213 suitable for a wet or washdown location?
No. The RACO 8213 is a UL Listed welded steel square box with open knockouts, intended for commercial and residential rough-in, splices, device mounting and conduit transitions in dry interior work. For a sealed environment, the Rittal 80181 JB series is a hinged-cover junction box rated IP66 / NEMA 4X. Use the enclosure rating to pick, not the footprint.
8) Does the RACO 8213 include a cover?
The 8213 is the box with clamps and knockouts; cover plates (flat blank or raised device covers) are ordered separately to suit whether you're closing it off as a junction box or mounting a device. If you want a junction box that arrives with its cover, the Cantex 5133690 is a 4-1/8 in. box supplied with a cover.
9) What should I use for a larger enclosure with a screw cover instead of a 4 in. square steel box?
The Carlon E987R is a polycarbonate screw-cover junction box measuring 6 in. x 6 in. x 4 in., which gives considerably more interior volume and a cover that fastens with screws. The RACO 8213 is a 4 in. square welded steel box, 1.5 in. deep, with integral AC/MC/Flex clamps for armored and metal-clad cable terminations. Choose the E987R for a large nonmetallic pull or splice point; choose the 8213 where a steel box is required for the metallic wiring method.
10) What is the manufacturer part number for the RACO 4 in. square box with AC/MC clamps and no bracket?
RACO 8213. One model covers it: 4 in. square, 1-1/2 in. deep, welded steel, AC/MC/MCI-A/flex clamps, no bracket.
