The DiversiTech® ISO-18 Iso-cube is an 18x18x3/4 in. natural rubber anti-vibration pad designed to reduce vibration and noise emanating from refrigeration or air conditioning equipment. The circular design in each pad offers a suction cup effect, which eliminates the need to bolt the pads down. The 18 in. pad can be cut or torn into eighty-one 2x2 in. segments. These 50 durometer pads will withstand a load of 180 psi with greater resiliency.
