iMBAPrice BE1R-2 2-Pack 1-Gang Ceiling Box Extender 4.35-Inch x 1.5-Inch video accessory

Two-pack ceiling box extender

This value pack supplies two 1-gang round ceiling box extenders in white plastic. They are designed to fit 3.5-inch and 4-inch round or octagonal boxes. Each unit measures 4.35-inch diameter by 1.5-inch depth. The plastic construction is trimmable to suit shallow boxes or obstructions.

Check existing box size and depth

Before ordering, verify that the ceiling box is a 3.5-inch or 4-inch round or octagonal type. Measure the current box depth to confirm whether the 1.5-inch extension provides the required additional space. Ensure the mounting surface can accept the 4.35-inch diameter footprint. The trim feature allows adjustment if the box is shallower than expected.

Integrates with standard ceiling boxes

The extender sits between the existing ceiling box and the fixture or cover, adding 1.5 inches of depth for wiring or device clearance. Trimmable plastic lets you reduce the profile where obstructions exist. It works with both round and octagonal boxes in the stated sizes. The two-pack covers multiple locations in a single project.
