The Arlington FB405 is the go-to shallow plastic pan box for ceiling fans and fixtures on 1/2 in or 5/8 in drywall. It works well on double joists or wood I-beams, and the centre screw, NM connector, mud cover and fan-bracket screws all ship installed. Arlington's own part listing spells out the split: UL listed for a 70 lb fan and 200 lb fixture, CSA listed for 50 lb fan and 50 lb fixture, and the CSA figure governs in Canada.
Why electricians pick it
- CSA listed 50 lb fan / 50 lb fixture; UL listed 70 lb fan / 200 lb fixture.
- Mounts to the joist with a ready-to-tighten centre screw; works on double joists and wood I-beams.
- Fan/fixture screws are parked in place, and combination hex/Phillips heads suit power drivers.

Pro tip from the counter
The "70lb/200lb" printed on many listings for this box is its UL rating. For a Canadian inspection, quote the CSA 50 lb figure to the customer at the counter, especially when they're picking out a heavy fan with a light kit.
Best for: production-home ceiling fan and light rough-in, I-joist and double-joist framing, end-of-run fixture locations, fire-rated ceilings
