Abstract:

A cabinet for air handling equipment includes a door assembly having features such as inner and outer door panels being held together and sealed by double-sided tape, which acts as a thermal break, a latch that prevents a door gasket from being crushed due to positive or negative air pressure within the cabinet, and a doorframe that is easy to assemble and install for either right-hand or left-hand swinging doors. To assemble adjacent pieces of the doorframe, sheet metal tabs of one piece are inserted into slits of the other piece. The tabs are then twisted to hold the adjacent pieces of the doorframe together.
