Crank Operator

Crank operation is primarily used in counter shutter applications where there is a wide counter space between the shutter and the user. You often see crank operation in lunchrooms or pharmacy counters. In that case, a rigid crank operation is ideal, since it can reach across the gap and open the shutter. Again, power is not required for this operation method, and it is best suited to infrequent daily cycles.
