ASRM-2xx Seismic Restrained Spring Mounts are heavy duty steel housing with built in all directional snubbing. The snubbing element is a high-quality molded neoprene. The steel housing and springs are galvanized which is suitable for outside application. The isolators are used in seismic applications where vertical and horizontal restraint is required due to reduced loads or external forces (wind loads). The springs sit in a neoprene acoustical cup which eliminates metal to metal contact. The in-built leveling bolt assembly passes through the elastomeric grommet that eliminates metal to metal contact. The mounting holes are furnished as standard; they are properly sized and spaced to provide maximum stability. Springs have 50% additional travel to max load as per ASHRAE recommendations.
