3-Gang Electrical Box Extender

The iMBAPrice BE3-1 is a three-gang electrical box extender designed to bring existing outlet boxes flush with new wall surfaces. It eliminates the need to remove or reposition the original box during renovation projects. This accessory is intended for standard electrical installations requiring a clean, code-compliant finish.

For installers updating wall depth

This extender suits electricians and renovators adding tile, panelling or thick drywall over existing boxes who need a flush-mount solution without rewiring. It is not intended for single-gang or two-gang applications, nor for use as a standalone junction enclosure. Buyers needing a different gang count or a weatherproof outdoor rating should look at other products.

Check gang count and box compatibility

Verify that the existing installation uses a standard three-gang box before ordering. Confirm the required extension depth matches the wall covering thickness being applied. Ensure the mounting screws align with the current box holes for a secure fit.

Questions about this item

Does this extender fit a standard three-gang electrical box already in my wall?

Yes, the BE3-1 is designed to extend an existing three-gang box so the device sits flush with the new wall surface without moving the original box.

Will my current outlets and switches still mount securely after adding this extender?

The extender adds depth to the existing box, allowing your original outlets and switches to fasten to the new flush surface just as they did before.

How can I confirm the extender is installed correctly once the wall covering is in place?

After installation, the face of the extender should sit perfectly level with the finished wall and the outlet or switch cover plate should sit flat with no gaps.
