The Everlock™ self-locking damper handle eliminates the need for any tools to unlock a damper handle, adjust the airflow, and lock it back into position. According to the manufacturer, it is designed to replace friction locks with the first positive (absolute) lock. It is fully hand-operated and takes two seconds to adjust and lock into place. To adjust, the user presses the thumb trigger and slides the handle into the desired position. Then, the user releases the thumb trigger and the spring-activated lock clicks into place. To readjust, the user presses the thumb trigger again and changes the position as desired. The damper handle is designed for use with both 1.5- and 2-inch standoff applications.
