 780CD Series 

  

rolling steel door 

The 780CD rolling sheet door is designed to fit openings up to 16' by 16' (4877 mm by 4877 mm) with ease, versatility, and good looks. The 780CD is designed for heavy-usage environments where a high windload-rated door is not required. Like the 790CW, this heavy-duty door is fabricated of high strength, 26-gauge galvanized steel curtain sections for superior performance. It also features Overhead Door Corporation's innovative quick-connect components that allow quick and easy assembly without sacrificing stability or durability. Stepped counterbalance rings and a unique curtain profile minimize nesting. The universal guide design further simplifies installation by allowing mounting directly to concrete, masonry, steel or wood jambs. Additional standard features such as dual rub strips on both edges of guide and a vinyl strip on both front edges of the curtain to minimize nesting ensure that the 780CD will provide long-lasting, lower-cost performance for years to come.
