Is the box UL or ETL listed?

Yes – it carries an ETL mark and complies with UL 514C. The assembly is also 2-hour fire-rated per UL 263.

What devices fit this 1-gang box?

Any standard North-American single-gang switch, dimmer, outlet, smart module or keystone plate up to 14 cu in conductor fill.

Can I install it in drywall after the wall is closed?

Absolutely. Swing-clamp ‘old-work’ wings tighten against existing drywall (½–1 in) with just a screwdriver—no studs or back-brackets required.

Does it support NM-B cable?

Yes. Integrated clamps accept #14-2 or #12-2 non-metallic sheathed cable; use bushings for low-voltage wire.

FAQ

What is an old work electrical box?
An old work box is selected for remodel and finished-wall installation where the wall surface is already in place. Confirm that the selected box style and mounting method suit the wall construction.

How do I choose the correct gang count?
Choose the gang count that matches the number of wiring devices in the wall layout. Review the selected variant's listed capacity, dimensions, and pack quantity before ordering.

Should I choose a single pack or contractor pack?
Choose a single pack for a repair or one installation point. Choose a larger pack when multiple matching boxes are required for the same project.
