nVent CADDY CAT Series Steel J-Hook, Cable Support Fitting

nVent CADDY CAT Series Steel J-Hook, Cable Support Fitting

The nVent CADDY CAT Series Steel J-Hook is a family of cable support fittings engineered for fast, secure routing of low-voltage and communications cabling above ceilings and along structural framing. The CAT Series spans five steel J-Hook models — CAT12, CAT16HP, CAT21HP, CAT32HP, and CAT64HP — sized from the 3/4-Inch CAT12 up through the higher-capacity CAT64HP, giving electrical and low-voltage contractors a single hook style to standardize on across a job site. Built from durable steel with an open-hook profile, every CAT Series J-Hook is designed for consistent, repeatable performance in commercial and industrial cable support systems.

Cable support hooks like the CAT Series are a staple of structured cabling projects, offering a simple alternative to J-hooks welded or clamped in place. By providing a dedicated steel support point in a range of sizes, the nVent CADDY CAT Series helps installers keep communications and low-voltage cable off of ceiling tiles, HVAC ductwork, and other trades' infrastructure, supporting cleaner overhead pathways throughout the job site.

Key Features

• Trade Size: The CAT Series lineup begins with the 3/4-Inch CAT12 and extends through the higher-capacity CAT16HP, CAT21HP, CAT32HP, and CAT64HP models for larger cable bundles.
• Durable Construction: Manufactured from steel for long-term strength and support in demanding commercial and industrial environments.
• CAT Series Design: A five-model lineup — CAT12, CAT16HP, CAT21HP, CAT32HP, and CAT64HP — engineered for efficient, repeatable cable routing across a range of bundle sizes.
• Open J-Hook Profile: Simplified hook geometry allows cable bundles to be set in place or removed without disassembling hardware.
• Model Options: Available under the CAT12, CAT16HP, CAT21HP, CAT32HP, and CAT64HP model designations from nVent CADDY (formerly Erico) for accurate specification and reordering.
• Overhead Cable Support: Designed to hold cable bundles above finished ceilings and along structural members, keeping runs organized and off other trades' equipment.
• Job-Site Consistency: Uniform CAT Series geometry allows contractors to standardize on a single hook style across a project for faster takeoffs and ordering.
