Mason Industries hd-green Lds Hanger 35 Lbs 3/8 Inch Rod

Product Description

The MASON INDUSTRIES hd-green is a double deflection LDS (limit duct support) hanger designed for vibration isolation in mechanical and HVAC systems. It accepts a 3/8-inch threaded rod and provides 0.20 inches of static deflection at a rated load of 35 pounds. The unit uses a green-coded elastomeric element to deliver resilient, level-plane isolation for suspended equipment, ductwork, and piping. HVAC mechanics and mechanical contractors install this hanger where low-frequency vibration transmission through structure-borne paths must be controlled. The compact housing measures 2.25 inches wide by 2.75 inches tall by 2.00 inches deep and ships at 3 pounds.

This hanger is suited for residential and light commercial mechanical installations where suspended ductwork, fan coil units, VAV boxes, or small air handlers require isolation from the building structure. It is typically installed in ceiling plenum spaces or mechanical rooms alongside continuous LDS pad systems. The double deflection design addresses both axial and lateral motion, making it appropriate for equipment subject to start-stop cycling or variable airflow conditions.

Key Features

• Double deflection elastomeric element provides 0.20 inches of static deflection at rated load
• Rated for 35 pounds load capacity per hanger point
• Accepts standard 3/8-inch threaded rod for straightforward integration with unistrut and clevis hanger systems
• Compact housing — 2.25 inches wide, 2.75 inches tall, 2.00 inches deep — fits tight ceiling cavities
• Color-coded green for quick load-range identification in the field
• California Proposition 65 compliant

Compatibility

Designed as an OEM-style vibration isolation hanger for suspended HVAC equipment, ductwork, and piping requiring a 35-pound rated, double deflection elastomeric mount on a 3/8-inch threaded rod.

Installation Notes

Installation is performed by licensed mechanical contractors or HVAC technicians. De-energize all associated equipment and relieve system pressure before replacing or repositioning hangers. Verify that the actual suspended load does not exceed the 35-pound rated capacity at this hanger point, as overloading the element reduces deflection performance and shortens service life. Follow applicable mechanical codes and manufacturer load tables when spacing hanger points along duct or pipe runs.
