nVent CADDY Series Pregalvanized Steel Adjustable Depth Box with Mounting Plate

nVent CADDY TB435 Series Adjustable Depth Box with Mounting Plate

The nVent CADDY TB435 Series is a pregalvanized, powder-coated steel adjustable depth box with an included mounting plate, offered in two box type configurations: the standard TB435 and the fire alarm-rated TB435FB. Both configurations share a 4-Inch x 4-Inch x 3-1/2-Inch box footprint, a pregalvanized steel body, and a powder-coated finish, sized for surface-mount installation in commercial and industrial electrical work. The included mounting plate simplifies secure, code-compliant device installation, whether the box is used for general electrical devices or, in the TB435FB configuration, to house and protect fire alarm system components. Formerly cataloged under the Erico name, the TB435 Series now carries the nVent CADDY brand while retaining the same steel fabrication and surface-mount box design electrical contractors rely on.
