The Dormakaba TS83 H/O is a heavy-duty, premium overhead door closer designed for a wide range of doors in commercial and institutional settings where a hold-open function is required. This versatile, non-handed unit features an adjustable closing force from EN3 to EN6, making it suitable for doors up to 1400mm wide and 120kg in weight. The key feature of this model is the mechanical hold-open function, which allows the door to be held securely open at a specific position, providing convenient access and ventilation. The closer also provides independently adjustable closing and latching speeds via two separate valves, ensuring precise control over the door's action. Finished in a durable Silver (SIL), the TS83 is fire-rated; however, for use on fire and smoke protection doors, the hold-open function must be disengaged to maintain compliance.
