Overhead door closer OTS 134
The overhead door closer OTS 134 is suitable for single-leaf doors with leaf widths up to 1100 mm and is tested and certified according to EN 1154. The closing force sizes 2, 3, and 4 can be flexibly adapted to your individual requirements – simply by repositioning the door closer and rotating the linkage bearing bracket. The valve functions for closing speed and latching action can be continuously adjusted from the front. Thermomatic valves ensure consistent closing performance even with temperature fluctuations, while safety valves protect the closer against overload. With a maximum opening and closing angle of 180°, the OTS 134 ensures controlled closing from any opening angle.
