Nodexa 4″ Square Box (1900) — 4″ × 4″ × 2″, 30 cu. in. Galvanized Steel (ETL)

The Nodexa 4″ Square Box — the "1900" every electrician already knows — is the high-volume junction that ties a rough-in together, splicing multiple circuits where a single-gang box would choke. Drawn from 1.1mm galvanized steel at a full 4 by 4 inches and 2 inches deep, it carries 30 cubic inches: real room for the wire nuts, pigtails, and crossing conduit runs a busy makeup pulls into one place, without the crowding that fails a box-fill check. The one-piece steel body gives conduit a rigid, crush-resistant anchor and holds grounding continuity that plastic can't match under a stud gun. Concentric 1/2″ and 3/4″ knockouts open on every face, so cable and conduit land from any direction, and a mud ring converts it from a pure junction box into a flush device mount for a switch or receptacle on a Scarborough infill build or a GTA commercial fit-out. ETL Listed under 4009580 for code-compliant residential and commercial wiring, it's a NorthLine Signature electrical part: stocked deep, priced for the contractor buying by the sleeve, built to be the box everything else lands in.
