Extension Ring

The ER-1501 Extension Ring addresses the challenge of improperly positioned 1501 Rough-in housings within walls. Patented for its utility, the extension ring compensates for housings set too deep by extending the sealing surface by 3/8” per ring, ensuring the fixture's proper sealing and alignment with the finished grade. Up to three rings can be stacked to achieve the desired adjustment. Constructed from die-cast, copper-free aluminum for longevity, each ring is finished in a durable Black polyester powder coat, designed to seamlessly integrate with existing Rough-In Section. This solution provides a straightforward fix to common installation issues, maintaining the integrity and aesthetics of 1501 installations.
