VMC Group Shear-Flex (Shearflex) Pads are elastomeric pad-type isolators that provide excellent high frequency sound attenuation in use directly under HVAC, power generation  and electrical equipment. Shear-Flex Pads are very effective in preventing shock and vibration transmission in non-critical installations. 

Shear-Flex Pads are molded elastomeric pads in a resilient cross-rib design. Standard sheet sizes are 18" x 18" x 3/8" thick and 18" x 36" x 3/8" thick. The segments can easily be cut to fit the required loading and shape of equipment bases. Shear-Flex Pads are available in three load ranges from 20 to 100 psi. The pads are molded in color-coded, oil-resistant, Durulene™ elastomer (weather-resistant) for easy identification and durability.

Shear-Flex Pads offer exceptional gripping - eliminating the need for bolting or cementing in most applications. Shear-flex Pads may also be used in multiple layers to increase deflection and are available pre-assembled, cut-to-size.
