Post and Rail Mounting
When mounting by post and rail, run the structural support the
full length of the unit. Locate the structural member at the base
of the unit as shown in Figure 27, assuring the I-beam is well
supported by the structural member.
If resilient material is placed between the unit and the rail,
insert a heavy steel plate between the unit and the resilient
material to distribute the load. Seal cabinet penetrations
(electrical, piping, etc.) properly to protect against moisture
and weather.
