A window or door system includes a frame adapted to be received within a window or door opening. A window or door unit is disposed on the frame, and a retainer is received by interference fit on either the frame or the window or door unit. The retainer has a portion that extends to engage the other of the frame and window or door unit, and to hold the window or door unit on the frame. The frame can be rectangular, for example, and the retainer may be linear extending along at least one edge of the frame. The frame can include an outwardly opening slot, and the retainer may be received by snap fit in the slot. |
