Steel City SP C3 CLAMP – Frequently Asked Questions
1) What is the Steel City C3 / C5 clamp used for?
It's a steel cable clamp that secures armored cable (AC) or metal clad cable (MC) where it enters a steel outlet or device box. The clamp holds the cable so the connection isn't taking strain, and it's sold individually, not in a kit or pack.
2) What is the difference between the Steel City C3 and C5 clamp sizes?
Both are ordered by clamp size code: C3 (MPN SP C3 CLAMP) and C5 (MPN SPC5CLAMP). Those two codes are the only options, so specify the size code that matches the AC/MC cable and box prep you're working with rather than a cable diameter.
3) Will this clamp work for NM (Romex) cable instead of MC?
No. The Steel City C3 and C5 clamps are specified for armored and metal clad cable. For nonmetallic sheathed cable you want a clamp or connector listed for NM, not this one.
4) Is this clamp made of steel or plastic?
Steel. That matters on commercial work where the box and raceway are metallic and the installer wants the clamp body to be the same material class as the enclosure rather than a plastic or die-cast snap-in fitting.
5) Does the Steel City cable clamp come with a knockout or a box?
No, it's the clamp only, with zero knockouts, and it's sold each. You supply the outlet or device box, and the clamp installs into the existing cable entry in that box.
6) Are Steel City C3 and C5 MC cable clamps made in the USA?
Country of origin is the United States. If you're on a public project with domestic sourcing language in the spec, that's the data point your submittal package needs.
7) How do I order enough clamps for a multi-box job?
Each clamp is priced and shipped as a single piece, so count one clamp per cable entry you need to secure and order that quantity in the size code you need, C3 or C5.
