Tech Products 51393 Vibration Isolator 210 Lb Stud Mount

Product Description

The TECH PRODUCTS 51393 is a stud-to-stud vibration isolator rated for a maximum load capacity of 210 pounds. This round, rubber-type mount is designed to absorb and dampen mechanical vibration between equipment and its supporting structure, reducing noise transmission and protecting connected components from fatigue. With a 3/8-16 thread size on both ends and an overall diameter of 1.5 inches, the 51393 installs between equipment bases and mounting surfaces in HVAC, refrigeration, and mechanical systems where vibration control is required. HVAC technicians and mechanical contractors are the primary installers of this hardware-type isolation component.

This vibration isolator is suited for residential and light commercial applications where rotating or reciprocating equipment generates vibration that must be isolated from the building structure. Common installations include small compressors, fan assemblies, air handlers, pump mounts, and similar mechanical equipment. The stud-to-stud configuration allows direct bolted installation without additional hardware when the mating thread pattern matches the 3/8-16 specification. The 1-inch overall height keeps the installed profile compact for tight clearance situations.

Key Features

• 210 lb maximum load capacity for reliable support of small to mid-size mechanical equipment
• 3/8-16 stud-to-stud thread configuration on both ends for straightforward bolted installation
• 1.5-inch diameter round body provides stable base contact and even load distribution
• 1-inch overall height suits installations with limited vertical clearance
• 0.625-inch thread length per stud end allows adequate thread engagement depth

Compatibility

Designed as a direct-mount vibration isolator for equipment with 3/8-16 threaded mounting points. Suitable for use in residential and light commercial HVAC, refrigeration, and general mechanical installations where a stud-type isolator with a 210 lb load rating is specified.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. Disconnect and lock out all power to the equipment before removing or replacing isolation mounts. Verify that the equipment load does not exceed the 210 lb rated capacity of this isolator and that the mating thread size is confirmed as 3/8-16 before installation. Do not overtighten the stud connections, as excessive torque can compress or damage the isolator body and reduce its vibration-damping effectiveness.
