Lord Heavy-Duty Plateform Mounts provide effective isolation against vibration. The contour of the flexing element was developed to provide uniform stress distribution. This, plus high strength bonding and the use of specially compounded elastomers, provides maximum service life.

These versatile mounts are available in three types, each type featuring square, diamond or holder configurations to suit a variety of design requirements. The three types, Plateform Mounts, Heavy-Duty Plateform Mounts and Multiplane Mounts, offer a range in load ratings from 0.5 to 600 pounds.

Snubbing washers provide an interlocking system of metal parts which act to prevent damage from overload or excessive shock impact.

Lord Plateform Mounts are easy to install and provide space efficiency. Typical applications include electronic equipment, business machines, medical equipment and small pumps, engines and gen sets.
