SC040404NK Carbon Steel Enclosure

The Wiegmann SC040404NK is a NEMA 1 rated junction box made from 16 gauge carbon steel with an ANSI 61 powder coated gray finish. It measures four inches high, wide and deep, providing a usable opening depth of 3.88 inches. The solid cover attaches with plated steel captive screws and the box includes self-tapping screws for installation. Embossed mounting holes allow direct wall mounting.

Indoor Electrical Junction Box Use

This enclosure suits electricians and installers needing a compact, screw-covered box for indoor wiring connections or small component housing. The CSA and cULus certifications support code-compliant installations in dry, non-hazardous locations. It is not intended for outdoor exposure, wash-down environments or applications requiring a hinged, windowed or gasketed cover. Buyers needing larger internal volume or higher NEMA ratings should consider other series.

Pre-Installation Mounting Checks

Verify the mounting surface can accept the embossed hole pattern and self-tapping hardware supplied with the unit. Confirm the 3.88 inch usable depth accommodates your terminal blocks, splices or devices with adequate wire-bending space. Ensure the captive screw closure meets your access-frequency requirements before ordering.

Questions about this item

What wall-mounting hardware must I already have to install the 4 in SC series enclosure?

The enclosure includes self-tapping screws and has embossed mounting holes, so you only need a drill and suitable wall anchors for your mounting surface.

Will the 16 ga carbon-steel body and ANSI 61 powder coat hold up next to older NEMA 1 enclosures in the same panel row?

Yes, the same NEMA 1 rating, CSA and cULus certifications, and gray ANSI 61 finish match legacy SC series units for consistent appearance and protection.

How do I confirm the captive screws are seating correctly after I close the solid cover?

Tighten the plated steel captive screws until the cover sits flush with the 4 in deep body; the usable opening depth of 3.88 in remains unchanged when fully closed.
