FLUSHTEK now offers users the option to install flush outlets with this durable, widely available PVC old-work box. These boxes are self-centering and install without screws, making the FLUSHTEK process even faster and easier. Users who already own a System Pack can purchase a Spare Box Template (select the "Lutron/Plastic Old Work" model) to make their System Pack compatible with Carlon Boxes. See our Carlon Upgrade Instructions for more information.
