Mountings - Neoprene Mountings
Double deflection neoprene mountings and double deflection rails are recommended for minor equipment or basement locations only. We have placed this limitation on all rubberlike materials because of their relatively minor deflections.
Neoprene mountings shall have a minimum static deflection of 0.35”(9mm). All metal surfaces shall be neoprene covered and have friction pads both top and bottom. Bolt holes shall be provided on the bottom and a tapped hole and cap screw on top. Steel rails shall be used above the mountings under equipment such as small vent sets to compensate for the overhang. Mountings shall be type ND or rail type RND as manufactured by Mason Industries, Inc.
