Type OM are free standing, open coil mounts. The spring is positioned between a steel bottom load plate, bonded to a neoprene noise stop pad, and a steel top load plate.
The spring is held in with two drilled and tapped steel restraints. The supported equipment is held between a levelling nut and retaining screw. The mounts may be fixed down utilising the pre‐drilled holes in the base plate.
Alternatively, the neoprene pad will act as a friction pad.
