Square steel stud box · 4 in x 4 in x 1-1/2 in, 21 cu in · wraparound steel stud bracket · 52151KSSX
What this product is for
This 4 in x 4 in x 1-1/2 in (102 x 102 x 38 mm) square steel stud box is used for new-work branch circuit rough-in where a metal box must be mounted directly to a steel stud. It provides 21 cu in of wiring space and accepts covers and mud rings sized for standard 4 in square boxes.
Use for
Use for junctions, conduit runs, armoured cable terminations where permitted by the box and fitting selection, and device installations with the correct raised cover or mud ring. Commonly used in commercial tenant fit-outs, multi-residential projects, and steel stud partition walls.
Avoid for
Avoid where a deeper box is needed for larger conductor fill, bulky splices, or device combinations that exceed 21 cu in capacity. Do not use without confirming box fill, support method, fitting compatibility, and local code requirements.
Best for
Best for electricians who need a shallow 4 in square box with an integral steel stud bracket for faster alignment on steel stud walls. It is a practical choice when standard 4 in square covers and accessories are already being used on the job.
Installed in
Typically installed in interior steel stud walls using the wraparound bracket. Distributor and catalogue references indicate this style is commonly used on 2-1/2 in and 3-5/8 in steel studs. Actual fit and finished wall alignment depend on stud type, wall build-up, bracket style, and installation method.
Why this product exists
This box combines standard 4 in square box capacity with a factory-attached steel stud support, reducing the need for separate brackets in new-work framing. The shallow 1-1/2 in depth helps where wall space is limited while still supporting many common junction and cover configurations.
Compared with similar products
Compared with a deeper 2-1/8 in box, this 1-1/2 in version takes less wall depth but offers less conductor space. Compared with a plain 4 in square box, the attached steel stud bracket can simplify mounting in steel stud partitions. As a rule of thumb, choose the deeper box when conductor count, fittings, or device volume may push box fill limits. Actual capacity requirements depend on conductor size, device count, grounding, and local electrical code.
