Exterior wall lights on stucco or siding need a box that seals to the sheathing without a bead of caulk. The Arlington FR405F is a non-metallic FR Series flanged pan box for exterior fixtures: wide flanges shed air and water, and interchangeable backs plus extension rings fit different wall finish thicknesses. It carries a light 10 lb fixture rating and is not intended for ceiling fans.
Why siding and electrical crews pick it
- Extra-wide flanges help block air and water around the box with no gasket or caulking.
- Ships assembled for a 1-3/8 in finish; flip the back for 5/8 in, or add the included ring for 7/8 in.
- High-strength polycarbonate body mounts flat to the wall surface.
- Includes 3/4 in and 1/4 in extension rings, an NM94 connector, a snap-in blank and screws.
- Up to a 10 lb fixture rating, suited to typical wall packs and porch lights.

Pro tip from the counter
Set the box for the finish before it goes on the wall: flip the back for 5/8 in stucco, add the 1/4 in ring for 7/8 in. Note that usable volume drops to 4.8 cu in at 5/8 in, so a light with a spliced feed-through may not fit at that setting.
Best for: exterior wall sconces and porch lights, stucco and flat-finish walls, siding and cladding retrofits, builders sealing the building envelope
