Abstract
An antiskid shock and vibration isolating foot is formed with an annular circumferential recess about midway between its top and bottom and made of a resilient elastomer. A threaded stud is bonded to the top of the elastomer. The upper portion above the annular recess passes through an opening in a case base until the edge around the opening resides in the annular recess. The threaded stud passes through an opening in the base of a component. The stiffness of the upper portion above the annular recess is different from the stiffness of the lower portion below the annular recess. The portion above the recess is frustoconical and that below is substantially cylindrical.
