A Latch Speed Latch control allows extra speed to be gained in the final stage of door closing to overcome the resistance of the door latch, door seals, or to overcome wind resistance or airtightness -without slamming. Also allows unlatched door to be closed quietly. B Sweep Speed The sweep control adjusts and regulates the speed of the door through the main arc of the closing sweep to suit individual needs. C Back Check - 70-180 degree (BC) Back check control provides a strength adjustable braking action - from about 90 degree to help prevent damage to door or wall if the door is opened with undue force. Door stops may still be needed D Delayed Action - 180-70 degree (DA) When the door is opened beyond approx. 70 degree, an integral delay function slows down the closing action for a period, to allow convenient passage through the opening. This feature is paticularly useful for hospitals, retirement homes and similar situations.
