ABSTRACT:
An adjustable roof jack interconnects a roof-mounted air handler with a duct opening through the roof of a building in a full range from flat to a 6-in-12 pitch; so that a single roof jack is capable of use in substantially all standard construction. To accomplish this, the roof jack includes a lower rectangular box-like member, which is attached to the roof. An upper rectangular box-like member is made for attachment to a roof-mounted air handler; and the front and sides of the upper box-like member extend downwardly over the corresponding side and front of the lower roof-mounted member. The upper member is pivotally connected to the lower member at pivot points located through the sides intermediate the front and back of the two members. The front of the members faces the center or higher portion of the roof; and the edge of the front of the upper member is folded into an "S" configuration; so that the upper edge of the front of the lower member extends into a pocket in the "S" configuration to provide a sliding seal between the two parts as the upper member is pivoted relative to the lower member to accommodate the roof pitch.
