The heavy-duty Crane bookfold door leaf mechanism is constructed from a high grade chilled bronze casting. All our revolving doors are furnished with Crane factory-made door seals, which are essential for the barrier blocking inside from outside environments. Crane doors are tested to meet the ASTM E283 standard, as well as to the even more stringent ASTM E783.
