The 74347U is an outdoor-rated surface-mount backbox built for field installations where flush mounting isn't an option. Die-cast construction and threaded conduit entries handle exterior and exposed environments without the weather concerns that come with standard stamped-steel gang boxes.

Built for the commercial installer

When a notification appliance needs to go on a concrete wall, metal panel, or exterior surface, a weatherproof backbox is the foundation of a clean install. The 74347U provides threaded conduit entries for watertight connections and a durable fire red baked enamel finish that matches the Kidde Commercial notification appliance line. Surface-mounts with rear mounting holes - no special hardware or adapters required.

  • Outdoor-rated construction: die-cast build with threaded conduit entries for weatherproof installations

  • Threaded conduit entries: multiple entry points on sides, top, and bottom for flexible conduit routing
