It is not possible to earthquake proof anything Our seismic restraints meet the Standard NZS-4104. Due to the unpredictable nature and ferocity of earthquakes, we cannot guarantee our earthquake restraints won’t subjected to forces that exceed their design specification.
Additionally effective restraint relies on the structural integrity of the surface to which they are attached and structural integrity of the item being restrained. Earthquake forces can cause the failure of the structure or collapse of the items being restrained. This is particularly true for heavily loaded book shelves.
