4 SQ EXPOSED WORK COVER (2) G

🔌 What it is

A 4-inch square exposed work cover designed to mount devices like duplex receptacles or GFCI receptacles onto a 4” square steel box in surface-mounted (exposed conduit) installations.

The “(2)” in your description typically indicates it supports two device openings or a dual-device configuration, depending on the exact variant (commonly duplex + GFCI layout).

🧾 What the shorthand means

• 4 SQ → Fits standard 4” square electrical box
• EXPOSED WORK → Used in surface-mounted conduit (not inside drywall)
• COVER → Device mounting plate for the box
• (2) → Supports two devices (commonly duplex + GFCI or dual device layout)
• G → Usually shorthand in inventory for GFCI-compatible opening

⚡ What it does

This cover:

• Converts a 4” square box into a usable device outlet location
• Provides mounting for duplex and/or GFCI receptacles
• Supports industrial/commercial exposed wiring systems
• Adds raised depth (typically 1/2") for device clearance and wiring space
• Allows installation of devices before or after mounting depending on design

Manufacturers describe these as industrial surface covers used to mount receptacles directly to 4” square boxes in exposed work environments.

🏠 Typical uses

• Warehouses
• Mechanical rooms
• Commercial garages
• Industrial facilities
• Surface-mounted EMT conduit systems
• Equipment wall drops
