Threaded Rod Vibration Dampers
Install between two lengths of threaded rod to reduce vibration in suspended equipment, such as air-handling units, pipe, and duct. Hex nuts are required for installation.
Dampers with spring and cushion allow for greater deflection (the distance the damper compresses) than dampers with a cushion alone.
Note: Capacity is for damper only. Mounting surface and fastening hardware will affect the ultimate capacity.

Corrosion-Resistant Swiveling
Extension Spring Stud Anchors
These stainless steel anchor studs offer excellent corrosion resistance. The head swivels 360° so the spring stays straight and properly coiled. Attach an extension spring to a stud and then thread the stud into your part for a secure connection. To make tightening easier, anchors have a hex socket on the bottom and wrench flats at the top of the threads.
