Description
The isolation mount is used to mount and locate systems, accommodate displacement, and isolate components from the surrounding structure (vibration, shock, noise).
Two-piece mounts are extremely versatile and include symmetric (two mounts) and asymmetric (mount plus pad) designs. They install in drilled holes in a support plate and are bolted through the center sleeve, either joined or loose.
