SRI-OTS 73x door-leaf coordinator for use on 2-leaf full-panic doors in escape and rescue routes
A suitable carrier bar must always be used with double-leaf full-panic doors installed in escape and rescue routes. This ensures that when the door is opened via the passive leaf (in emergency situations), the active leaf is carried at least as far as the beginning of the action range of the (SRI-OTS 73x) door leaf coordinator.
