Abstract
The specification discloses a door light providing improved drainage, improved sealing between sashes, and improved sealing between frame components. Brackets are mounted on the sill at discrete locations to hold the screen and the movable sash off the sill to provide drainage and eliminate capillary action which would otherwise draw moisture to the frame interior. The meeting rails include resiliently deflectable interlock flanges which engage and are biased against one another when the movable sash is closed to improve the seal therebetween. A frame trim piece interfits with the frame body and deflects a resiliently deformable flap integral with the frame body to effect a weather seal between the trim piece and frame body.
