Carlon E981EFNL – Frequently Asked Questions

1) What trade sizes does the Carlon E981 fire-rated PVC box come in?
The Carlon E981 one-gang box is offered in 1/2 inch, 3/4 inch, and 1 inch hub trade sizes, each available loose or by the carton. Ordering codes run E981DFNL (1/2 inch loose) and E981DFN-CTN (1/2 inch carton), E981EFNL and E981EFN-CTN for 3/4 inch, E981FFNL and E981FFN-CTN for 1 inch. Match the hub size to the PVC conduit you are running into the box.
2) How many wires can I get into an 18 cubic inch junction box?
The Carlon E981 gives you 18 cubic inches of usable volume in a single gang, which is the figure you plug into your NEC box fill calculation. Subtract the allowances for the device, clamps, and grounds, then count conductors at the cubic-inch value for their gauge. It is sized for through terminations, so splicing a couple of circuits through a single gang is the intended use.
3) Does the Carlon E981 box have knockouts, or do I have to use the molded hubs?
No knockouts. The E981 ships with zero knockouts, so every entry is through the molded threaded hubs, and the hub size is set by which variant you order (1/2, 3/4, or 1 inch). If you need a second raceway entry into a spot the hubs don't face, this is the wrong box for that opening.
4) Will a standard FS box cover fit the Carlon E981?
Yes. All sizes of this box take standard covers, accessories, or devices, so a common one-gang FS/FD blank, duplex, switch, or GFCI cover will land on it. The cover and gasket are separate items, not included with the box.
5) Is this Carlon box UL listed for a fire-rated wall assembly?
The E981 carries UL file E11461 and is a fire-rated PVC box. Its stated application is through terminations. For a rated wall, the assembly listing governs how many boxes, what spacing, and what putty pad or backing the inspector expects, so pair the box with the tested assembly detail you are building to.
6) Can I use a PVC box like this outdoors or in a damp location?
The E981 is molded PVC, which does not rust or corrode the way a steel FS box does, and that is why non-metallic FS bodies get used in wet and washdown areas. Weatherproof performance depends on the cover and gasket you put on it plus properly cemented hub connections, so specify a gasketed weatherproof cover for anything exposed.
7) What is the depth of this 1-gang Carlon box?
2.30 inches deep, one gang, gray PVC. That depth is what gets it to 18 cubic inches while staying shallow enough for surface mounting on a wall or column without the body standing far off the finish.
8) Should I order the carton or the loose box?
Same box either way. Loose (E981DFNL, E981EFNL, E981FFNL) suits a service call or a small punch list where you need a handful. The carton codes (E981DFN-CTN, E981EFN-CTN, E981FFN-CTN) are the bulk pack for a rough-in where you are setting dozens of the same trade size.
9) Is the Carlon E981 made in the USA?
Yes, country of origin is the United States. That matters if you are bidding public or institutional work with domestic sourcing language in the spec.
