Best For
Common scopes where the Arlington 931 (and the rest of the Conduit Bodies line) earns its place on the spec. This isn't an exhaustive list, but a fast read on whether this is the right family for your application before you go deeper on the cut sheet.
- Conduit direction changes at walls

- Pull-point access for long runs

Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet, so there are no jurisdictional surprises at inspection.
- Cover gasket, access geometry, and conductor-bend radius all sized to the body trade-size so the pull doesn't stall at the cleanout.
- 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, 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
- Conduit bodies (LB/T/C) must not contain splices unless listed for that purpose and properly sized for the conductor count per CEC 12-3036.
-
Primary code reference: CEC Section 12-3022 (Conduit Bodies); CEC 12-3036 (Number of Conductors).
- 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 Conduit Bodies line. Most of them are small and avoidable when the right SKU and accessory get pulled at the counter.
- Splicing inside a standard LB (not listed for splices)
- Skipping the gasket on outdoor installs
- Choosing aluminum where non-metallic is required
- Forgetting the cover kit (sold separately on most models)

Frequently Asked Questions
-
Is the Arlington 931 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.
-
Form factor: LB, T, C, LL, LR?
Varies by configuration. Check the 931 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.
-
Trade size?
The 931 is a 3/4" trade-size fitting.
-
Aluminum body or non-metallic?
The 931 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.
-
Cover and gasket included?
Confirm against the published Arlington 931 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 splices (most LBs are not)?
Maple Electric Supply can pull the 931 spec sheet on request. The answer depends on the specific configuration and the listed conditions of use, and anything affecting code compliance should come straight from the manufacturer's current published documentation.
