The DiversiTech® ISO-2 Iso-cube is a 2 in. x 2 in. x 3/4 in. natural rubber anti-vibration pad designed to reduce vibration and noise emanating from refrigeration and air conditioning equipment. The circular design in each pad offers a suction cup effect, which eliminates the need to bolt the pads down. These 50 durometer pads will withstand a load of 180 psi with greater resiliency.
