Seismic Zone 2 Capability: The housings and anchor bolts are optimally designed for seismic zone 2

applications.

Superior Isolation Efficiency: Series "820" spring isolators consist of welded housings and 1 inch

deflection spring elements to provide excellent isolation of vibration over a wide frequency range.

Lateral Stability: Free-standing springs are laterally stable and designed to provide 50% overload capacity.


Vertical Limit Stops: Adjustable vertical limit stops control vertical and lateral movement of isolated

equipment due to load change, and lateral seismic load.

Easy To Install:
Built-in leveling bolt eliminates shimming in all applications, and save installation costs.


Effective Noise Reduction: The resilient washers under the springs effectively interrupt structure-borne

noise transmission paths to prevent noise amplifications caused by sounding-board effect. The resilient
washers replace the neoprene base pad to allow solid connections of anchor bolts and base plate.
