Carlon B121BFBR – Frequently Asked Questions

1) Can this Carlon adjustable floor box be installed in a concrete pour?
No. The Carlon B121 Adjust-A-Box floor box kit is built for residential wood sub-floor construction, not concrete. If your opening is a poured slab or an on-grade pour, you need a concrete-rated floor box instead. For wood framing, the adjustable body lets you set the cover flush once the finish flooring goes down.
2) Does the Carlon B121 floor box come with the receptacle, or do I order that separately?
The duplex receptacle is included in the kit, so the box arrives ready to wire and trim out. You supply the branch circuit cable, connectors and fasteners for the sub-floor.
3) Does the Carlon floor box adjust after the finish floor is installed?
That is the point of the Adjust-A-Box design: the box height is adjustable so the cover can be brought flush to whatever finish material goes over the sub-floor, whether that is hardwood, tile or carpet with pad. Rough it in to the sub-floor, then set final height at trim-out.
4) What color options does the Carlon single-gang floor box kit come in?
Three finishes: brass, ivory and white. Brass is the usual pick when the box lands in a finished hardwood or carpeted living space, and ivory or white are matched to device color rather than the floor.
5) The spec says zero knockouts. How do I get the cable into this floor box?
Zero knockouts is correct for this Carlon Adjust-A-Box kit, so there are no stamped punch-outs to pry. Entry is through the box's provided ports rather than field-opened knockouts, which keeps the body sealed against debris from the floor cavity and leaves no sharp stamped edge to nick the cable jacket.
6) Will one Carlon B121 floor box handle a two-gang setup for power and low voltage?
No, it is a single-gang box and carries one duplex receptacle. For a station that needs both power and data or AV, set a second box for the low voltage side, keeping the required separation between the power and communications conductors.
7) Is this Carlon floor box made in the USA, and whose label is on it?
Manufactured in the United States and labeled Steel City. Useful if you are on a job with domestic sourcing requirements or you are matching submittals that list Steel City floor boxes.
