Durdyne 30351 Cable Lock Steel Ductwork Suspension

Product Description

The DURDYNE 30351 is a steel cable lock designed for suspending ductwork and mechanical equipment in commercial and residential HVAC installations. Part of the Dyna-Tite line, this cable lock provides a fast, reliable method for securing suspended loads without the need for specialized tooling during adjustment. Each lock is rated for a specific wire size and is engineered with a 5:1 safety factor ratio built into its working load range, giving installers confidence in the connection under real-world load conditions. The easy-release pin allows simple position adjustments on the fly, reducing installation time on the job site.

This cable lock is used in HVAC mechanical installations where ductwork, air handlers, VAV boxes, and similar equipment must be suspended from structural members. It is suited for both new construction and retrofit applications where hanging hardware needs to be set quickly and repositioned without tools. HVAC technicians and sheet metal workers are the primary trade installing this type of hardware in accordance with applicable mechanical codes.

Key Features

• Steel construction for durable load-bearing performance in suspension applications
• 5:1 safety factor ratio incorporated into the working load range
• Designed for use with one specific wire size for consistent, reliable grip
• Easy-release pin allows tool-free adjustments during installation
• Fast installation process reduces labor time on the job site

Compatibility

Designed as an OEM-style suspension hardware replacement for use in HVAC ductwork and equipment hanging applications where a single-wire-size cable lock is required.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers following local mechanical code requirements. Confirm the wire size used on the job matches the specific wire size this cable lock is rated for before installation. De-energize and secure any equipment before making adjustments to suspension hardware supporting energized components. Use the easy-release pin for repositioning rather than forcing the lock, which can compromise grip integrity.
