Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet. No jurisdictional surprises at inspection.
- Listed for the connection type, raceway diameter, and environment the box requires: set-screw, compression, and concrete-tight variants all live in the same Arlington line.
- 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, this is the same part number you've already spec'd on prior jobs, with the same listings.
- Replacement and add-on availability through a Canadian supply channel means short-notice job sites can pull additional units without re-engineering the order.

Installation Notes
- EMT couplings and connectors must be listed for the application per CEC 12-1400. Concrete-tight or rain-tight fittings required where exposed.
-
Primary code reference: CEC Section 12-1400 (EMT); CEC 12-1402 (EMT Couplings/Connectors).
- Verify the Arlington listing on the current spec sheet matches your local AHJ's adopted code edition. 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 EMT Fittings line. Most of them are small, and all are avoidable when the right SKU and accessory get pulled at the counter.
- Using set-screw in concrete (needs concrete-tight)
- Using indoor-rated in wet locations
- Skipping the bushing on the conductor side
- Forgetting the bonding lockring for grounding through the fitting

Sourcing in Ontario
For contractors specifying the Arlington 824ART on a project, Maple Electric Supply can confirm in-stock counts before you commit on the bid, which is 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 824ART 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 EMT trade size does this fit?
The 824ART is a 1-1/2" trade-size fitting.
-
Set-screw, compression, or push-on style?
Varies by configuration: check the 824ART 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.
-
Concrete-tight, rain-tight, or both?
The 824ART 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.
-
Steel or zinc die-cast body?
Confirm against the published Arlington 824ART 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.
-
Listed for grounding/bonding through the fitting?
Maple Electric Supply can pull the 824ART 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.
