Dortec DT-63 SILVER is a universal closer with a typical folding lever, which is installed on top of the canvas and door frame on the left or right.
Depending on the width and weight of the door, the closer must apply an increased force to close the door, overcoming the force of inertia, air resistance or friction in the hinges. Therefore, this model has EN3 closing force indicators, a maximum door width of up to 1070 mm, an opening force of 45-65 kgf with a cycle life of 1 million. The speed and strengthening of the door closing is adjustable. Doklap allows you to determine the acceptable speed of the door within 15-20 ° of smooth final closing, overcoming the influence of external factors.
The device can additionally be equipped with a latch in the open position, a plastic cover, a parallel pull bracket, or a damper that prevents sudden opening by braking under wind or mechanical impact.
Operating temperature from -40°C to +55°C allows the door closer to be used indoors and outdoors. The color is white.
