Galvanized Steel Enclosure 18x18x4
This NEMA 1 rated enclosure is built from 16 gauge galvanized steel with a silver finish. It measures 18 inches high by 18 inches wide by 4 inches deep. The solid cover attaches with plated steel screws and the box includes self-tapping screws for installation. Embossed mounting holes allow for direct wall mounting.
Upgrade from open wiring or non-rated boxes
The jump is worth it when you need a UL Listed and CSA Certified enclosure that meets cULus standards. It provides a secure, grounded housing for circuit breakers and line protection components in indoor environments. The galvanized construction resists corrosion better than untreated steel alternatives. Usable opening depth is 3.88 inches for component clearance.
Limits of NEMA 1 indoor rating
This standard protects against falling dirt and contact with live parts only. It does not protect against water, oil, dust or corrosive agents. The screw-on cover requires tools for access and does not form a gasketed seal. Installers must ensure the mounting surface supports the steel weight and that conduit entries match the enclosure knockouts.

Questions about this item
What size mounting holes does the 18x18x4 enclosure use?
The SC181804GNK has embossed mounting holes designed for wall mounting; use the included self-tapping screws to secure it to the surface.
Which step do installers often miss when fitting the cover?
After positioning the solid cover, tighten the plated steel screws evenly to maintain the NEMA 1 seal; skipping the cross-pattern tightening leaves gaps.
Will the galvanized finish need recoating after installation?
The galvanized steel finish is rated for indoor NEMA 1 use and does not require recoating under normal conditions.
