The present invention generally relates to the making of a base isolation device to be used for the protection of non-structural items and equipment. When the base plate, which is attached to the ground, moves with the ground earthquake shakings, the isolation plate, supported by the roller ball transfer bearings, rolls over the base plate and prevents the transfer of forces to the overlying equipment. Once the ground shaking ends, the tension springs or viscous dampers pull back the isolation plate to its original position, laterally and rotationally. The height of the isolation device could be as low as 3 inches.
