Easy installation
With the use of specially designed hinges on the side of the frame (optional), installation is done without the need to use guides resulting in reduced application time and trouble-free assembly.
Adjustable locks
The pressure on the tires can be fluctuated through the adjustable locks (which are placed on the spaniels, the tilting shears and the reinforcements), thus preventing the air circulation between the leaf and the frame and ensuring the correct insulation of the space.
The mechanism of prevention of misuse during the opening or tilting operation, excludes the combined operation and prevents the causing of damages from strong winds.
