Adjustable Depth Box with Mounting Plate
nVent CADDY Adjustable Depth Box with Mounting Plate is a pre-galvanized adjustable depth box for mounting fire alarm devices and strobes, designed for on-stud and between stud applications. With two screws inside the box, installers can easily adjust to different depths after installation of drywall or ceiling tiles.
Available in three different options, designed for a wide range of applications. The TB425 is for 2.5” stud depths. The TB435 is for stud depths 3 5/8” and greater. The four-square box with ½” offset design is a ready-to-install assembly for devices and strobes that do not require a mud ring.
The TB425S option is for stud depths 3 5/8” and greater. The four-square box with no offset design allows for a mud ring to be used for mounting smaller devices for both single- and double-layer drywall.
