Ensures that double-leaf doors do not jam when the inactive leaf is accidentally pushed first during opening. The function of a closing sequence controller is only guaranteed if the active leaf is opened to a certain angle at least. If the inactive leaf is pushed first, the follower flap ensures that the active leaf always opens sufficiently until the closing sequence controller can support it. This allows it to ensure the correct closing order. Includes base and swivel plate as well as an adjustable support foot. Please observe standard or application regulations!
