Empire 21LSS0075 C-clamp Locknut 630 Lb 3/4 Inch Rod

Product Description

The EMPIRE 21LSS0075 is a C-clamp with locknut designed for securing threaded rod to structural flanges in mechanical, HVAC, and plumbing suspension applications. Constructed from 304 stainless steel, this clamp delivers corrosion resistance suitable for wet or chemically active environments. It accepts a 3/4 inch rod and accommodates a maximum flange thickness of 3/4 inches. The locknut design holds the clamp firmly in position once set, reducing the risk of slippage under sustained load. Load capacity is rated at 630 pounds. Licensed HVAC technicians, plumbers, and pipefitters install this hardware when suspending pipe hangers, duct supports, or equipment from structural steel beams and channels.

This clamp is used in commercial and light industrial mechanical rooms, rooftop equipment installations, and building infrastructure projects where threaded rod suspension systems are common. It is appropriate for both new construction and retrofit work where corrosion resistance is a priority, such as indoor pool mechanical rooms, coastal installations, or food-service facilities. The 304 stainless steel construction makes it well suited for environments that would degrade carbon steel hardware over time.

Key Features

• 630 pound load capacity for reliable support of pipe, duct, and equipment hangers
• Accepts 3/4 inch threaded rod suspension systems
• Fits flanges up to 3/4 inches thick
• 304 stainless steel construction resists corrosion in wet and chemically active environments
• Integrated locknut secures clamp position and prevents loosening under vibration
• Sold individually, making it practical for single-unit replacement or small-quantity installs

Compatibility

Designed as an OEM-style replacement or new-install fitting for standard 3/4 inch threaded rod hanger systems used in mechanical, plumbing, and HVAC suspension applications with flanges up to 3/4 inches thick.

Installation Notes

Installation is performed by licensed mechanical, plumbing, or HVAC contractors following applicable building and mechanical codes. Verify that the structural flange and threaded rod are clean and free of debris before attaching the clamp. Tighten the locknut securely using appropriate hand tools to ensure the clamp does not shift under load. Do not exceed the rated 630 pound load capacity, and confirm that all supporting structure is rated for the intended suspended weight.
