Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet, so there are no jurisdictional surprises at inspection.
- Weight-rated boxes with the bracket geometry to land on standard joist spacing, with no field-fabricated supports and no warranty conversations later.
- Distributed by a Canadian-owned stocking dealer. Maple Electric Supply ships from Ontario, so the SKU lands on site without cross-border duty calcs or week-long customs holds.
- Backed by Arlington's North American manufacturing footprint. It's the same part number you've already spec'd on prior jobs, with the same listings.
- Replacement and add-on availability runs through a Canadian supply channel, so short-notice job sites can pull additional units without re-engineering the order.

Installation Notes
- Ceiling fan boxes must be rated for the fan weight per CEC Section 30. Fire-rated assemblies require fire-rated boxes per local code.
-
Primary code reference: CEC Section 30 (Lighting Installations); CEC 12-3000 (Boxes and Fittings).
- Verify the Arlington listing on the current spec sheet matches your local AHJ's adopted code edition, since provincial amendments to the CEC can override the federal base text.
- Confirm trade size, mounting style, and accessory pairing against the project drawings before ordering in volume. Maple Electric Supply's counter staff can pull the cut sheet on request.
- Installation must be completed by a qualified electrician where required by local code; the homeowner / unlicensed scope is narrower in Ontario than in several US jurisdictions.
Common Mistakes to Avoid
Patterns we see on returns, callbacks, and inspection re-visits around the Fan and Fixture Boxes line. Most of them are small and avoidable when the right SKU and accessory get pulled at the counter.
- Using a fixture-rated box for a fan (weight failure)
- Skipping fire-rated boxes in a fire-rated assembly
- Forgetting the joist-hanger model for new construction
- Sealing without checking vapor-barrier compatibility

Sourcing in Ontario
For contractors specifying the Arlington FBB900 on a project, Maple Electric Supply can confirm in-stock counts before you commit on the bid. That's useful when the install window is tight or the substitution clause in the spec is closed. Larger orders qualify for project pricing, and replacement SKUs ship from Ontario stock instead of waiting on a cross-border backorder.
Frequently Asked Questions
-
Is the Arlington FBB900 UL and/or CSA listed?
Arlington components are listed for the applications stated by the manufacturer. Always verify the listing on the product's spec sheet against your jurisdiction's adopted code.
-
Is this part made in the USA?
Arlington Industries manufactures the bulk of its catalog in the United States. Confirm origin on the current spec sheet if it matters for your project.
-
What's the fan weight rating?
Varies by configuration. Check the FBB900 datasheet for the exact dimensions, ratings, and accessory list before ordering in volume. Arlington updates spec sheets periodically, so spec the live version from the manufacturer's site for the current job.
-
New construction or retrofit (cut-in)?
The FBB900 datasheet is the authoritative source on this. Arlington publishes torque specs, listed conductor ranges, and accepted accessories per part number, and those values shift between revisions even when the SKU stays the same.
-
Fire-rated assembly compatible?
Confirm against the published Arlington FBB900 cut sheet; values shift between configurations even inside the same family. Maple Electric Supply can email a current copy on request and flag any recent revisions that changed listed ratings.
-
Air-tight / vapor barrier rated?
Maple Electric Supply can pull the FBB900 spec sheet on request. Answers here depend on the specific configuration and the listed conditions of use. Anything that affects code compliance should come straight from the manufacturer's current published documentation.
-
Stud-mount, joist-mount, or pan-style?
Refer to the FBB900 product page on Arlington's site or contact Maple Electric Supply for a copy of the current spec sheet with all listed ratings. Generic family-level guidance is a starting point, but the SKU-level sheet is what the inspector will reference.
