Steel City 72 C 1RD – Frequently Asked Questions
1) Does the 72C1 square cover have any device or fixture openings?
No openings at all. It's a flat blank cover with zero knockouts, so it closes off a 4-11/16 inch square box completely. If you need to bring a device, fixture stud, or conduit through, choose a device ring or a knockout cover rather than this one.
2) Can I use this steel blank cover in a damp location or does it need to be a different material?
The 72C1 is pre-galvanized steel, which gives it corrosion protection for typical indoor and damp interior work, and the vaportight version adds sealing where vapor is a concern. For directly wet, washdown, or corrosive chemical environments, a cover rated for that duty is the better call than a pre-galvanized steel plate.
3) I have an unused 4-11/16 junction box in a ceiling. Is this the right part to close it off?
Yes. A flat blank steel cover is the standard way to keep a 4-11/16 inch square box accessible but closed, which is what code expects for a junction box left in service with splices inside. Screws thread into the box's own cover ears, so nothing else is needed beyond the cover itself.
4) Are Steel City 72C1 covers sold individually or by the box?
The selling unit is each, so you can order the exact count you need rather than a full carton. Useful when you're closing off a handful of abandoned or spare junction boxes rather than rough-in for a whole floor.
