Panic flap MK 1

The closing squence ensures that the active and passive leaf are closing in the correct order, e.g. the passive leaf first, active leaf last. The function of the closing sequence is only given if the active leaf is opened up to a certain angle. If the passive leaf is opened first (full panic version), the panic flap ensures that also the active leaf opens to such extend that the closing sequence can control the active leaf. Material: steel with nylon roll, zinc-plated (silver colour) Tested by the material testing office (MPA-NRW).
