Best For
Common scopes where the Arlington 8081FGC (and the rest of the Siding Mounting Blocks line) earns its place on the spec. This isn't an exhaustive list, but it's a fast read on whether this is the right family for your application before you go deeper on the cut sheet.
- Vinyl siding builds
- Cementboard / Hardie
- Stucco light fixtures
- Brick / masonry retrofits
Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet, so there are no jurisdictional surprises at inspection.
- Sized to common cladding profiles so the block sits flush, the J-channel meets clean, and the receptacle gasket actually seals against the siding face.
- 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
- Mounting blocks must be installed before siding to maintain weather-tight seal. J-channel integration where applicable.
-
Primary code reference: CEC Section 12 (Wiring Methods); CEC 26-700 (Wet Location Equipment).
- 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 Siding Mounting Blocks line. Most of them are small, and all of them are avoidable when the right SKU and accessory get pulled at the counter.
- Choosing a vinyl block on Hardie (different J-channel depth)
- Mounting before flashing
- Skipping the caulk seal at the perimeter
- Painting before priming the paintable surface

Frequently Asked Questions
-
Is the Arlington 8081FGC 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.
-
Which siding type is this designed for?
Varies by configuration. Check the 8081FGC 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 8081FGC 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.
-
Paintable?
Confirm against the published Arlington 8081FGC 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.
-
Does the block include the J-channel integration?
Maple Electric Supply can pull the 8081FGC spec sheet on request. The answer here depends 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.
-
Mounts what kind of fixture (light, GFCI, hose bib)?
Refer to the 8081FGC 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.
