ABSTRACT:
A curb for a roof air conditioning package is enclosed on all sides and the bottom to form a plenum. The air conduits from and to the building are connected to the plenum rather than the unit. The plenum is reinforced by a wood collar around the top, which then serves as a second function of a roofing nailer strip. The curb is leveled by wedge supports.
