Tech Products 51356 Stud/stud Vibration Isolator 105 Lb

Product Description

The TECH PRODUCTS 51356 is a stud-to-stud vibration isolator designed to reduce structure-borne noise and mechanical vibration in HVAC, refrigeration, and industrial equipment installations. Rated for a maximum load capacity of 105 pounds, it features a 5/16-18 threaded stud mount on both ends and measures 1.5 inches in diameter by 1 inch in height. The round isolator profile allows for straightforward inline mounting between equipment bases and support frames. HVAC technicians and mechanical contractors install this type of isolator on compressors, fan assemblies, condensing units, and similar vibration-generating components where isolation from the mounting structure is required.

This isolator is suited for residential and light commercial HVAC applications where a compact, threaded mount solution is needed. Typical installations include rooftop unit supports, compressor mounting pads, and air handler bases. The stud-to-stud configuration allows direct integration into existing threaded mounting points without requiring additional hardware adapters. The 5/16-18 thread size is a common standard in equipment mounting assemblies, making this a practical drop-in option for a range of equipment types.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. Power down and de-energize the equipment fully before removing or replacing isolators under load-bearing components. Ensure the equipment weight per mounting point does not exceed the 105-pound rated capacity of this isolator. Consult applicable mechanical codes for vibration isolation requirements in your jurisdiction.
