Arlington Industries FBR415F Non-Metallic Ceiling Fan/Fixture Vapor Box with Adjustable Steel Bracket, 18.3 Cu. In.

The Arlington Industries FBR415F is a non-metallic ceiling fan/fixture vapor box engineered for installations where maintaining an airtight, vapor-sealed ceiling assembly is essential. Molded from durable plastic, this vapor box offers 18.3 cu. in. of interior capacity for wiring connections and features an adjustable steel bracket that lets installers position the box to match joist spacing before fixtures or ceiling fans are mounted. Measuring 2.658" in size, the FBR415F is built to fit standard ceiling cavities while keeping the vapor barrier intact around the electrical penetration, helping preserve the energy efficiency of the ceiling assembly.

Key Features

  • 18.3 Cu. In. Capacity: Generous interior volume accommodates wiring splices and connections for ceiling fan or fixture hookups.
  • Non-Metallic Construction: Molded plastic housing resists corrosion and will not conduct electricity, a durable alternative to metal boxes.
  • Adjustable Steel Bracket: Integrated steel bracket adjusts to align the box precisely with the ceiling opening and joist spacing.
  • 2.658" Profile: Compact sizing designed to fit standard ceiling framing and vapor barrier assemblies.
  • Vapor Box Design: Purpose-built to preserve the continuity of a vapor barrier where ceiling fan or fixture wiring penetrates the ceiling.
  • Ceiling Fan Support: Suitable for supporting ceiling fan and light fixture installations where a vapor box configuration is required.
  • Adjustable Positioning: The bracket's adjustability simplifies alignment during rough-in, reducing installation time and improving fit accuracy.

Arlington Industries FBR415F – Frequently Asked Questions

1) Will the Arlington FBR415F support a ceiling fan, or is it fixture-only?
The FBR415F is a ceiling fan/fixture box, so it is built for supporting ceiling fan and light fixture installations where a vapor box is required. It mounts on an integrated adjustable steel bracket that spans between joists rather than relying on the plastic housing alone.
2) What does a vapor box like the FBR415F do that a standard plastic ceiling box doesn't?
It keeps the ceiling's vapor barrier continuous where the fan or fixture wiring penetrates the ceiling. On an air-sealed assembly, a standard box leaves an opening in the barrier at every ceiling penetration. The FBR415F is molded specifically to seal around that penetration, which is why it gets specified on energy-code jobs and in insulated ceilings below unconditioned attic space.
3) How much wiring capacity does the FBR415F give me for a fan hookup with a switched light?
18.3 cubic inches of interior volume. That is the working space for the splices on a fan and fixture hookup, including the incoming feed and switch legs. Fill calculations for conductors, clamps, and the fixture stud are done per NEC box fill, so count your conductors against that 18.3 cu. in. before you add extra circuits to the box.
4) Can I line the FBR415F up with my joist spacing during rough-in?
Yes. The steel bracket adjusts, so the box can be slid along the bracket and positioned to hit the ceiling opening where the fan or fixture needs to land instead of being fixed at the joist face. That is the reason to pick this over a fixed-ear box when the fixture location does not fall next to a joist.
5) Is the Arlington FBR415F metal or plastic, and does it need bonding?
Non-metallic, molded plastic. A plastic box does not conduct, so there is no box to bond, but the equipment grounding conductors still have to be spliced together in the box and carried to the fan or fixture. If your job spec calls for a metal box, this is not the part.
6) What exact part number do I order for the Arlington 18.3 cu. in. ceiling vapor fan box?
Arlington Industries FBR415F. One model, sold as the box with its adjustable steel bracket already integrated.
7) Is the FBR415F suitable for a remodel, or only new construction?
Both are listed applications, new construction and remodel, along with residential and light commercial work. Practically, the bracket wants access to the joists, so in a remodel it suits an open or removed ceiling rather than a cut-in through finished drywall.
