LIMITATIONS
Columbia elevator doors are limited to maximum opening sizes as shown in the table above. Each door panel has a maximum size nominally 32" wide by 122" high (standard certification label applications). [Taller doors are allowed for oversize applications as noted in the table above.] Installation must be into code compliant fire resistant rated structures (walls, sills, hardware) as contained in this listing. [For drywall wall applications a 3 hour listed wall design must be used. Installation in listed masonry walls is optional.] Door and frame assemblies are to be marked with the Warnock Hersey certification label outlining the fire protection of the elevator doors.
