ProStar™ Model 770SS

​The Model 770SS rolling sh​eet door is a great option for facilities that require a quality door that installs quickly, operates dependably, and requires minimal maintenance.

Stepped counterbalance rings and a unique curtain profile ensure a tight curtain wrap resulting in a smooth operating door and minimal nesting. A host of other standard features from standard roller bearings and dual rub strips on both guide edges and both front edges of the curtain further promote smooth operation and longer life. Available in 12 standard colors, the Model 770SS represents a good choice and a good value.
