Tech Products 51556-2 Vibration Isolator 410 Lb Stud/stud

Product Description

The TECH PRODUCTS 51556-2 is a stud/stud vibration isolator rated for loads up to 410 pounds. It is designed to absorb and dampen mechanical vibration and noise transmitted through equipment mounting points in HVAC, mechanical, and industrial installations. The isolator measures 3-1/8 inches in diameter and 3 inches in height, with a 1/2-13 threaded stud on each end for direct inline mounting. HVAC technicians and mechanical contractors install this type of isolator between equipment bases and structural supports to protect building structure and connected equipment from vibration-induced wear and noise transfer.

This isolator is suited for residential and commercial HVAC equipment mounting applications, including rooftop units, condensing units, air handlers, fans, pumps, and compressor bases. The stud/stud configuration allows it to be installed inline on threaded rod or mounting hardware. It is appropriate for any mechanical installation where load-rated vibration attenuation is required at a threaded connection point.

Key Features

• 410-pound maximum load capacity for medium-duty mechanical equipment mounting
• Stud/stud configuration with 1/2-13 threaded ends for inline installation on threaded rod
• 3-1/8-inch overall diameter provides stable footprint for load distribution
• 3-inch overall height accommodates standard equipment mounting clearances
• Absorbs vibration and reduces structure-borne noise transmission

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for HVAC, mechanical, and industrial equipment requiring a 1/2-13 stud/stud mount with up to 410 pounds of load capacity per isolator.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors during equipment startup or scheduled maintenance. De-energize and lock out all equipment before servicing mounting hardware. Use appropriately rated threaded rod and hardware rated for the full equipment load. Verify that the combined isolator load rating meets or exceeds the actual equipment weight before installation.
