Isotop SD
Steel spring isolators— Natural frequency from 3.2 Hz— Electro-galvanised or cathodic dip-coated (CDC) for
increased corrosion protection— Secure connection between the plate and the spring
thanks to special adhesive— M 10 internal thread— Suitable base plate and/or height adjustment available— Base plate with damping element (FP/K) also isolates
higher frequencies— Simple load control thanks to open design— Spring design conforms to DIN EN 13906–1
