Specialty Roof Curbs
Units to be mounted on a roof curb not supplied by Trane require special attention.
Center the unit base on the roof curb (see Figure 18).
A typical unit roof curb and unit base cross-section without a pipe cabinet is shown in Figure 19.
Tab le 4 lists the outside-to-outside dimensions for over all width and length of the roof curb for each
size unit. Length is dependent on the various unit options ordered. Refer to submittals for section
