Expertly designed for maximum safety, the KI-SB4 Detector Base is a must-have for any home or business. This standard base fits perfectly with a 4 inch square box and includes a TS4 skirt for added protection. Trust the KIDDE brand to provide top-of-the-line products to keep your space secure.

Detector mounting bases have wiring terminals that are accessible from the "room-side" after mounting the base to the electrical box. The bases mount to North American 1-gang boxes and to 3½ inch or 4 inch octagon boxes, 1½ inches (38 mm) deep. They also mount to European BESA and 1-gang boxes with 60.3 mm fixing centers. The KI-SB4, KI-RB4, and KI-IB4 mount to North American 4 inch sq. electrical boxes in addition to the above boxes. They include the GSA-TS4 Trim Skirt, which is used to cover the "mounting ears" on the base. The KI-ABST mounts to a 4 inch square box only. With their versatility and ease of installation, these detector mounting bases provide a reliable and efficient solution for a wide range of applications.
