Door sizing information is based on installation on
standard weight doors, 7'0" (2.13m) high 1-3/4" (44mm) thick; hung on
anti-friction hinges and operating under normal conditions. Doors in excess of 7'8"
(2.34m) high or 1-3/4" (44mm) thick, unusually heavy doors or doors subject to wind
or draft conditions will generally require the next larger size closer.
