Vision panels provide outside visibility and allow light entry through the 5” x 17” panel. Constructed of a translucent polycarbonate panel inside a glossy white 20 gauge frame, the panels create no interference with the operation of the door. The location and number of vision panels are limited by the door size. Ask a sales representative for details. Frames are only available in Gloss White and are only available on the series 2000 and 2500. Not available on doors with 9 ½” drums or windload doors.
