Wiremold 880CS3-1 3-gang Cast Iron Floor Box

Product Description

The WIREMOLD 880CS3-1 is a 3-gang cast iron floor box designed for below-grade electrical installations in concrete and raised floor applications. Cast iron construction provides the structural durability required in commercial and light industrial environments where the floor box must bear foot traffic and equipment loads. Licensed electricians install this unit during rough-in, setting it in concrete forms or retrofit-cutting into existing slabs to provide flush, code-compliant access to electrical circuits at floor level.

This floor box is suited for commercial office buildings, schools, retail spaces, and industrial facilities where floor-mounted electrical access is required. The 3-gang capacity accommodates multiple receptacle or device combinations in a single opening, reducing the need for multiple floor penetrations in open-plan environments.

Key Features

• 3-gang configuration supports multiple devices in a single floor penetration
• Cast iron body provides high impact resistance and load-bearing durability
• Designed for flush floor installation in concrete or raised-floor assemblies
• Compatible with standard floor box covers and receptacle trim plates

Compatibility

Designed as an OEM-style replacement and standard-fit floor box for 3-gang flush floor electrical installations in commercial construction applications.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 314 requirements for floor boxes. Power must be de-energized and locked out before any wiring connections are made. When setting in concrete, position and level the box before the pour and protect the interior from concrete intrusion. In retrofit applications, confirm the rough opening dimensions match the box footprint before cutting.
