The Chain and Sprocket Drive option is by far the most economical opening assist device we offer. This is a manually operated aid which assists in the opening and closing of the yoke bolts. These units not only make the process faster, they also prevent the uneven movement of the yokes which may cause binding. On larger closures, ratio reduction is available to further ease the force required to turn the unit. Hand wheels can also be furnished which provides faster operation and eliminates the need for additional tools. More information >>
