Tech Products 51556-4 Vibration Isolator 910 Lb

Product Description

The TECH PRODUCTS 51556-4 is a heavy-duty stud/stud vibration isolator rated for a maximum load capacity of 910 pounds. It features a round profile measuring 3.125 inches in diameter and 3 inches in height, with 1/2-13 threaded studs and a thread length of 1.625 inches on each end. Designed to isolate mechanical vibration and reduce noise transmission, this isolator is installed between a vibrating component and its mounting surface. HVAC technicians, equipment installers, and mechanical contractors use this type of isolator in commercial and industrial applications where equipment-generated vibration must be controlled.

This isolator is suited for use with rooftop HVAC units, air handlers, compressors, pumps, fans, and other mechanical equipment mounted to structural surfaces. The stud/stud configuration allows inline mounting between equipment feet and base rails or mounting pads. Its 910-pound load rating makes it appropriate for medium to heavy commercial equipment installations where vibration attenuation is a system requirement.

Key Features

• 910-pound maximum load capacity for medium to heavy equipment support
• Stud/stud mount type with 1/2-13 thread size for secure inline fastening
• 1.625-inch thread length on each stud end for adequate engagement
• Round shape, 3.125 inches in diameter and 3 inches in height
• Reduces vibration transmission between mechanical equipment and mounting structure

Compatibility

Designed as an OEM-style replacement or direct-fit vibration isolator for mechanical equipment installations requiring a 1/2-13 stud/stud mount with a 910-pound load rating.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. Power down and lock out all equipment before servicing mounting hardware. Thread engagement should be verified on both stud ends before torquing fasteners; do not over-tighten to the point of compressing the isolator beyond its design deflection. Follow applicable mechanical codes and equipment manufacturer guidelines for vibration isolation requirements.
