Arlington Industries FB442 – Frequently Asked Questions

1) Which Arlington L-shaped fan box do I order for a 2-hour fire-rated ceiling assembly?
The FB443F. It is the 18.3 cu in version carrying the 2-hour fire rating. The FB442 (13.4 cu in) and FB443 (18.3 cu in) are the non-fire-rated versions, so on a rated ceiling in a corridor, demising assembly, or stair enclosure the FB443F is the only one of the three that belongs there.
2) FB442 vs FB443 - how do I know which cubic inch size I need?
Count your conductors. The FB442 gives 13.4 cu in and the FB443 gives 18.3 cu in. A fan box that only takes a single 14/2 or 12/2 feed and the fan leads fits the 13.4. Once you are splicing a feed plus a switch leg, or running 12 AWG with a separate light kit conductor, the box fill math pushes you to the 18.3 cu in FB443. The fire-rated FB443F is also 18.3 cu in, so stepping up to fire rating costs you nothing in volume.
3) Does the Arlington L-shaped fan box work with 5/8 inch drywall?
Yes, and with 1/2 inch. The FB44X series is built for either 1/2" or 5/8" drywall, so the same part number covers a residential ceiling and a commercial or multi-family assembly running the heavier board. The flange seats flush to the finished surface in both cases.
4) How does the L-shaped fan box mount - does it need a joist?
It fastens to the side of the ceiling joist. The L-shaped profile hooks over the joist face and the flange lands against the drywall plane, which is what carries the 70 lb fan and 200 lb fixture load back into framing. That means you need wood framing at the fan location. There is no bar hanger or between-joist brace in this design, so if the fan has to land in the middle of a bay you need a different support product.
5) Do I still need a separate air sealing gasket at the ceiling penetration for an energy code inspection?
Not with this box. The L-shaped profile seals the ceiling penetration itself, which is the point of the shape, and the box is specifically built to protect against air infiltration. For a blower door test or an energy-code retrofit that is the ceiling box handled without a foam pan or a caulked collar on top of it.
6) Does the Arlington fan box need painting or will it corrode in a damp ceiling?
Black plastic, corrosion resistant, no painting required. That is a practical difference from a steel pancake or octagon box in a laundry, bath, or parking-structure ceiling where a metal box eventually rusts at the fasteners.
7) How many Arlington FB442 fan boxes come in a box, and are they made in the USA?
Standard pack is 25 pieces, and Arlington manufactures the FB44X series in the United States. For a multi-family or tenant-improvement job that is one carton per 25 fan locations, which is useful when you are pricing out a whole floor.
