Years of experience in designing and manufacturing this hardware
has led DYNAIR engineers to a simple, new approach.
Opposed Action Dampers have traditionally required a special
high and low bracket. This is no longer necessary . . . only two
brackets are needed for all normal dampers. Also, DYNAIR’s
compression ring/locknut clamp replaces set screws. Steel parts
are zinc plated to industry specifications.
