  • Panel optimized for edge stiffness and gasket compression
    Patent number: 6742990
    Abstract: An air handler enclosure includes a sheet metal panel fastened to a frame of the enclosure with a gasket sealingly compressed between the frame and the face of the panel. The outer edges of the panel are folded over to create a hem that overlays the face of the panel. The gasket is placed against the face of the panel, just inside the inner periphery of the hem. When the panel is installed, the hem abuts the frame to serve as a spacer that keeps the face of the panel a certain distance away from the frame. In this way, the hem prevents the gasket from being over compressed or crushed between the frame and the face of the panel.
