Notes:
1. All dimensions are inches, interpreted per ANSI Y14.
2. Refer to next page for installation instructions.
3. Mount molded in weather resistant duralene compound as standard. Also available in other materials
such as natural rubber, extreme high temperature silicone, high-damped silicone, nitrile and EDPM.
4. AL = Mounting hole center to center spacing.
5. HF = Free height of mount, prior to loading. Operating height calculated by the free height less the
static deflection under load. All dimensions for reference only.
6. Hardware zinc-electroplated.
