Nvent Caddy CAT1258SM Hammer-on Flange

Product Description

The NVENT CADDY CAT1258SM is a hammer-on flange designed for fast, tool-free attachment to structural flanges in the 5/16 inch to 1/2 inch thickness range. This hardware fitting snaps onto beam flanges and similar steel members to provide a secure anchor point for threaded rod, wire, or other hanging hardware. It is commonly used in commercial and industrial construction to support mechanical, electrical, and plumbing systems from structural steel. Installation requires no drilling or welding, making it a preferred choice for electricians, pipefitters, and mechanical contractors working overhead on steel framing.

This hammer-on flange fits flanged structural steel members within the 5/16 inch to 1/2 inch thickness range. It is suited for use in commercial buildings, industrial facilities, and institutional construction where conduit, pipe, ductwork, or cable tray must be suspended from I-beams, purlins, or similar steel structural elements. Sold individually, it integrates with standard threaded rod and compatible CADDY support hardware commonly found in mechanical and electrical overhead installations.

Installation Notes

Installation is performed by licensed electricians, pipefitters, or mechanical contractors as part of overhead support systems. Before installing or adjusting overhead hardware, ensure all adjacent energized systems are de-energized and proper fall protection is in place when working at height. The fitting is driven onto the flange by hand or with a mallet and should be verified as fully seated before loading. Follow applicable NEC, IPC, or IFGC requirements for support spacing and load ratings on suspended systems.
