Product Description

The LEVITON TELCOM 3099F-1Y is a single-gang rubber box single extension fitting designed for use in electrical and low-voltage wiring installations. This hardware accessory provides a secure, flexible interface at the box opening, accommodating conduit or cable entry points where a durable rubber fitting is required.
