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.

Key Features

  • Trade Size: 4-Inch x 4-Inch x 3-1/2-Inch box dimensions are shared across the TB435 Series for a compact footprint in tight mounting spaces.
  • Durable Construction: Pregalvanized steel body resists corrosion for long-term reliability in commercial and industrial settings.
  • Powder-Coated Finish: A powder-coated exterior adds an extra layer of protection against wear along with a clean, uniform appearance.
  • Mounting Plate Included: An integrated mounting plate simplifies secure, code-compliant installation of electrical or fire alarm devices and hardware.
  • Two Box Type Configurations: Specify the standard TB435 for general device mounting or the TB435FB configuration, purpose-built to house and protect fire alarm system components.
  • Compact Steel Housing: The 4-Inch x 4-Inch x 3-1/2-Inch steel housing keeps the footprint small while still accommodating mounted devices.
  • TB435 Series: Part of the nVent CADDY TB435 Series adjustable depth box line, sized 4-Inch x 4-Inch x 3-1/2-Inch for straightforward specification.

nVent CADDY TB435 – Frequently Asked Questions

1) What is the difference between the nVent CADDY TB435 and TB435FB adjustable depth box?
Both are the same 4 x 4 x 3-1/2 inch pregalvanized steel box with a powder-coated finish and a mounting plate included. The difference is the configuration you order: TB435 is the standard box for general device mounting, and TB435FB is the fire alarm box configuration, built to house and protect fire alarm system components such as pull stations. Same footprint, same fabrication, so the choice comes down to whether the box is serving a fire alarm device or general electrical work.
2) Does the TB435 box come with a mounting plate or do I have to buy one separately?
The mounting plate is included with both the TB435 and TB435FB. You do not order it as a separate item. The plate is what you fasten the device or hardware to, which keeps the install straightforward on both the standard and fire alarm configurations.
3) Is the nVent CADDY TB435 box suitable for a surface-mount installation in an electrical room?
Yes. The TB435 is sized for surface-mount work, and the 4 x 4 x 3-1/2 inch housing keeps the footprint small in tight mounting spaces. Typical placements are electrical rooms and utility closets, corridors and common areas, and both new construction and retrofit electrical installations.
4) I used to buy this box under the Erico name. Is the nVent CADDY TB435 the same part?
Same product line. The TB435 Series was formerly catalogued under Erico and now carries the nVent CADDY brand, keeping the same steel fabrication and surface-mount box design. Order by TB435 for the standard box or TB435FB for the fire alarm configuration.
5) How many box sizes does the nVent CADDY TB435 Series come in?
One size. The 4 x 4 x 3-1/2 inch footprint is shared across the TB435 Series, so the only ordering decision is box type: TB435 or TB435FB. If you need a different footprint, this series will not get you there.
6) Will a pregalvanized steel box hold up in a damp industrial space?
The TB435 body is pregalvanized steel, which resists corrosion, and the exterior carries a powder-coated finish for an added layer of protection against wear. That combination is why it gets specified for commercial and industrial installations rather than clean office-only work.
