Nvent Caddy CAT12912SM Hammer-on J-hook Pipe Support

Product Description

The NVENT CADDY CAT12912SM is a hammer-on J-hook designed for fast, tool-free attachment to structural steel framing. It supports pipe, conduit, or tubing in the 0.5 to 0.75 inch diameter range. The hook drives directly onto the flange of a beam or strut with a single mallet strike, eliminating the need for drilling, welding, or separate fasteners. Plumbers, pipefitters, and electricians use this type of fitting to hang runs of pipe or conduit from steel structure in commercial and light industrial settings. It is sold individually and is part of NVENT CADDY's hammer-on support line.

This J-hook is suited for interior commercial construction where pipe or conduit must be supported from steel I-beams, C-channels, or similar structural members. Typical applications include mechanical room pipe runs, electrical conduit routing, and low-voltage cable support where a clean, permanent attachment to exposed steel is required. The hammer-on design speeds up installation on new construction projects where multiple support points must be set quickly across a steel structure.

• Single-piece construction for fast field installation
• Sold individually (unit of measure: each)

Compatibility

Designed as an OEM-style support fitting for use with pipe, conduit, or tubing measuring 0.5 to 0.75 inches in diameter, installed onto compatible structural steel framing members.

Installation Notes

Installation is performed by plumbers, pipefitters, or electricians working on steel-framed structures. Confirm the structural member flange thickness is within the hook's rated grip range before striking. Drive the hook onto the beam flange using a hammer or mallet with firm, controlled blows — do not pry or lever the hook after seating. Follow applicable mechanical and electrical codes, including IPC and NEC, for pipe and conduit support spacing requirements.
