The SVI series seismic restrained open spring mounts are engineered to provide effective vibration isolation while offering all-directional restraint against vertical and horizontal forces caused by seismic activity and high wind loads. These mounts combine high-performance steel springs with a rugged welded steel housing to ensure equipment stability, safety, and long-term durability in demanding HVAC and mechanical applications.

SVI mounts are tested and certified to ANSI/ASHRAE 171-2017 for wind and seismic load resistance, making them suitable for use in critical installations where code compliance and equipment protection are required.

Configuration: bolt-top with leveling adjustment
Maximum Vertical Seismic Load Resistance: 4,860 lbs
