Empire 24LB0038 Purlin Clamp 3/8 Inch Rod 400 Lb

Product Description

The EMPIRE 24LB0038 is a purlin clamp designed to suspend threaded rod from structural steel purlins in overhead mechanical, electrical, and plumbing installations. Built from ductile iron, it accepts a 3/8 inch diameter threaded rod and carries a rated load capacity of 400 pounds. The ductile iron construction provides greater impact resistance than standard gray iron, making it suitable for demanding commercial and industrial environments. This clamp is a standard component in suspended piping, conduit, and duct hanger assemblies installed by licensed mechanical and electrical contractors.

The 24LB0038 is used in commercial and industrial construction where threaded rod hangers must attach to structural purlin members. Typical applications include suspended HVAC ductwork support, conduit runs, and piping systems where purlins serve as the primary overhead structure. It is commonly specified in pre-engineered metal buildings and warehouse-style construction where open-web or cold-formed steel purlins are the standard framing element.

Key Features

• Ductile iron construction for improved toughness and impact resistance versus gray iron
• 400 pound rated load capacity for heavy hanger assemblies
• Accepts 3/8 inch threaded rod — the most common hanger rod size in light commercial applications
• Single-piece clamp design mounts directly to purlin flange without welding or drilling
• Sold individually, compatible with standard 3/8 inch threaded rod stock

Compatibility

Designed for use with 3/8 inch diameter threaded rod in standard purlin clamp hanger assemblies. Fits typical cold-formed or structural steel purlin flanges as found in pre-engineered metal building construction.

Installation Notes

Installation is typically performed by licensed mechanical, electrical, or plumbing contractors following applicable local building codes and OSHA overhead work requirements. Verify that the purlin flange thickness and width fall within the clamp's designed engagement range before loading. Do not exceed the 400 pound rated load capacity, and ensure the threaded rod is fully engaged and fastened with the appropriate nut and washer below the clamp. De-energize any nearby electrical systems and follow fall-protection protocols when working at height.
