The SmarTork™ Spirator is a revolutionary elevator door closer designed to overcome wind shaft velocity as the door closes. The SmarTork’s patent-pending helical groove design provides more tension in the door-closed position than in the door-open position—actually regaining tension as it closes the door. The SmarTork cuts energy costs and reduces callbacks associated with wind shaft velocity issues.
