nVent CADDY 512SA/512SAT Adjustable T-Grid Box Hanger, Pregalvanized Steel

The nVent CADDY Adjustable T-Grid Box Hanger, offered in the 512SA and 512SAT configurations, gives electricians and ceiling contractors a fast, secure way to mount electrical and outlet boxes directly to suspended T-grid ceiling systems. Formed from pregalvanized steel, this family of hangers resists corrosion while standing up to the daily demands of commercial ceiling work. The adjustable design lets installers position boxes precisely across the T-grid span without cutting or drilling into the grid itself, helping crews keep box placement consistent from room to room. Both the 512SA and 512SAT carry the trusted Caddy® name that electrical contractors have relied on for dependable, code-friendly support hardware on commercial jobsites.

Key Features

  • Two Model Configurations: Available as the 512SA and 512SAT, so crews can select the mounting configuration that best fits the T-grid ceiling system on the job.
  • Adjustable Mounting: The hanger extends and adjusts to align boxes exactly where they are needed across the ceiling grid span, simplifying layout in rooms with varying grid dimensions.
  • Durable Pregalvanized Steel Construction: Pregalvanized steel construction delivers long-term corrosion resistance and structural strength for demanding commercial environments, including plenum spaces above finished ceilings.
  • T-Grid Mounting Design: Engineered to attach directly to standard suspended ceiling T-grid systems for quick, tool-friendly positioning without additional brackets or hardware.
  • Reliable Box Support: Holds outlet, junction, and fixture boxes securely in place above suspended ceilings, keeping installations level, stable, and properly aligned with the finished ceiling plane.
  • Installer-Friendly Design: The adjustable hanger arm is designed for quick field positioning, helping installers reduce time spent measuring and custom-fitting box supports on site.
  • Caddy® Brand Dependability: Backed by nVent CADDY, a long-recognized name in fastening and support solutions for electrical and mechanical trades on commercial and institutional projects.

nVent CADDY 512SA – Frequently Asked Questions

1) How does the nVent CADDY 512SA box hanger attach to a suspended ceiling without drilling the grid?
The 512SA mounts directly onto standard suspended ceiling T-grid, clipping to the grid member itself, so there is no cutting or drilling into the grid to set a box. The hanger arm adjusts across the grid span, which is how you square a box up to the finished ceiling plane instead of custom-fitting a support on site.
2) What is the difference between the CADDY 512SA and 512SAT?
They are two mounting configurations of the same adjustable T-grid box hanger family, ordered as separate part numbers: 512SA and 512SAT. Pick the one that matches the T-grid ceiling system on the job. Both are pregalvanized steel and both mount to standard suspended T-grid.
3) Can these CADDY T-grid hangers hold a junction box in a plenum space above the ceiling?
Yes. The hanger supports outlet, junction, and fixture boxes above a suspended ceiling, and the pregalvanized steel construction is called out for use in commercial environments including plenum spaces above finished ceilings.
4) Do I need extra brackets or hardware to install a CADDY 512SA on ceiling grid?
No additional brackets or hardware are needed for the grid attachment itself. The hanger is built to go straight onto standard suspended T-grid and position by hand in the field. You still supply the box and its own fasteners.
5) Will one part number cover rooms with different ceiling grid dimensions?
That is the point of the adjustable arm. The 512SA extends and adjusts along the grid span, so a crew can hold one part number on the truck and still land boxes consistently in rooms where the grid layout changes, rather than cutting a support for each opening.
6) Is a pregalvanized steel box hanger good enough for a damp commercial ceiling space?
Pregalvanized steel is the material on the 512SA and 512SAT, chosen for long-term corrosion resistance in commercial interior ceiling spaces. It is an interior support finish, not a coastal or wet-location stainless spec, so for genuinely wet or corrosive environments look at a stainless or post-galvanized support instead.
