Hubbell 3FB 3-gang Blank Wall Plate Cover

Product Description

The HUBBELL 3FB is a 3-gang blank wall plate cover designed to close off unused multi-gang electrical boxes. It provides a clean, finished appearance at box locations where no devices are installed, keeping openings properly enclosed in compliance with standard electrical box cover requirements. Electricians install this cover during rough-in finish work or when consolidating device layouts that leave one or more gangs empty. The blank face offers no cutouts, so no switch, outlet, or other device can be mounted to it.

This cover plate is suited for residential and light commercial electrical installations where a 3-gang box is present but no devices occupy all gang positions, or where a full blank cover is needed for a spare or decommissioned box location. It is a straightforward finish item used by licensed electricians and experienced DIYers during panel trim-out or renovation work.

Key Features

• 3-gang blank face with no device cutouts for clean box closure
• Sized to fit standard 3-gang electrical boxes
• Suitable for finish-out of unused or spare box locations
• Low-profile cover for flush wall appearance

Compatibility

Installation Notes

Installation is performed by a licensed electrician or qualified installer. Always de-energize the circuit at the breaker and verify with a non-contact voltage tester before working in or around the box. Secure the cover plate with the appropriate screws for the box type. Work should conform to applicable NEC requirements for box fill and cover installation.
