Electrical Outlet Box Extender

The iMBAPrice BE4-2 is a four-gang outlet box extender designed for electrical contractors and installers. It allows compliance with the 2008 NEC article 314.2 when an electrical box is set back from the finished wall surface. The device levels and supports wiring devices such as standard switches, receptacles and GFCIs in both handy boxes and four-inch square boxes with plaster rings. It provides an adjustable extension up to one and one-half inches.

Compatibility Check

Before ordering, verify that the existing electrical box is either a handy box or a four-inch square box fitted with a plaster ring for single devices. Confirm the box setback does not exceed the maximum adjustment range of one and one-half inches. Ensure the wiring devices to be installed are standard switches, receptacles or GFCIs compatible with the extender's mounting configuration.

Build Integration

The extender is manufactured from 94V0 rated flame-retardant plastic rated for 105°C continuous use, providing a secure mounting platform for devices in recessed boxes. It bridges the gap between the box and the wall finish, freeing the installer from cutting back the wall surface or replacing the box. The white finish blends with standard wall plates and devices for a clean appearance.

Questions about this item

Does the iMBAPrice BE4-2 package include mounting screws or a cover plate, or must they be purchased separately?

The extender is designed to level and support standard switches, receptacles, and GFCIs in set-back boxes; mounting hardware and cover plates for the specific device are not included and must be sourced separately.

Should I choose this extender for a standard handy box or a 4-inch square box with a plaster ring?

This model works with both handy boxes and 4-inch square electrical boxes fitted with plaster rings for single switches or receptacles, providing up to 1-1/2-inch of adjustment depth.

What does the 94V-0 rating mean for safety once the extender is installed behind a receptacle?

The 94V-0 rated plastic resists flame spread and self-extinguishes, while the 105°C continuous-use rating ensures the material maintains integrity under normal operating temperatures inside the wall.
