General Description N/A Lord Grommet Isolators are designed and produced with the same kind of precision and care as our high performance bonded elastomeric mounts. This provides close control of stiffness and dimensions. You get the performance and quality you need at low cost.

Standard Grommet Isolators are made of neoprene and natural rubber. They provide good vibration isolation for disturbing frequencies above 30 Hz. Damped Grommet Isolators are made of SPE®/D Elastomer. They are well suited to applications which involve limited sway space.
