The SR 390 is a thoroughly proven, purely mechanical door coordinator for twinleaf fire and smoke check doors. It is face-fixed to the door frame.
The SR 392 is a co-ordinator for double-wing fire and smoke check doors. It is installed so that it is concealed either in the lintel or below the door frame. It is non-handed and is suitable for combinations of unequal door leaves. The correct closing sequence of the door leaves is always ensured by the holding arm (active leaf) and the release roller (inactive leaf).
