Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet, so there are no jurisdictional surprises at inspection.
- Solves a specific install problem: box-fill remediation, retrofit cut-in, or fixture-weight upgrade, without a custom fabrication line item.
- 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
- Box extenders must restore proper box volume per CEC 12-3036. Retrofit boxes must be securely fastened per CEC 12-3010.
-
Primary code reference: CEC Section 12-3000 (Boxes & Fittings); CEC 12-3022 (Box Fill).
- 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 Specialty Boxes line. Most of them are small and avoidable when the right SKU and accessory get pulled at the counter.
- Using a box extender without confirming the box-fill math
- Choosing a non-fire-rated box in a fire-rated assembly
- Mounting a retrofit box on a wet wall
- Skipping the matching cover

Sourcing in Ontario
For contractors specifying the Arlington FBC42253BR on a project, Maple Electric Supply can confirm in-stock counts before you commit on the bid, which helps 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 FBC42253BR 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 box volume / cu. in.?
Varies by configuration. Check the FBC42253BR 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?
The FBC42253BR 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?
Confirm against the published Arlington FBC42253BR 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.
-
Gangable to expand?
Maple Electric Supply can pull the FBC42253BR 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.
-
Cover / blank included?
Refer to the FBC42253BR 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.
