Wayne Dalton Corp.’s 800 HC and 800C HC rolling doors have high-cycle motors with built-in braking and direct-drive gearboxes. A floor-level controller has a built-in, non-resettable cycle counter and digital readout with time delay and self-close timer. The 800 HC and 800C HC doors have springless barrels and do not require a counterbalance system. They are produced in steel, aluminum and stainless steel. The maximum size is 20 feet wide by 20 feet high. Four standard polyester finishes are available: Gray, Beige, White and Brown.
