Arlington Industries 939 4-gang Box Cover with Gasket

Product Description

The ARLINGTON INDUSTRIES 939 is a 4-gang electrical outlet box cover supplied with a cover gasket. It provides a weatherproof or air-tight seal between the cover plate and the electrical box, helping to block drafts, moisture, and dust from entering the wall cavity. Electricians and electrical contractors install this cover as part of rough-in and finish work on residential and light commercial projects. The included gasket eliminates the need to source a separate foam or rubber seal, keeping the installation clean and code-ready in a single unit quantity.

This cover and gasket assembly is suited for use on 4-gang electrical boxes in standard wall and ceiling applications where a sealed finish is required. Typical scenarios include exterior walls where air infiltration control is a priority, as well as installations near damp or dusty environments. The gasket compresses against the box face when the cover is fastened, forming a continuous seal around the perimeter of the cover plate.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify the absence of voltage before handling any wiring or cover components. Align the gasket flush against the box face before seating the cover plate to ensure a proper seal. Do not overtighten fasteners, as excessive force can deform the gasket and reduce sealing effectiveness.
