Structural elements of the screen (box, rails, end-slat) are made of extruded aluminum, which ensures durability and resistance for many years of use. A special clip helps adjust the height of the mesh closure. Installing the system to the lintel is very fast and simple, thanks to the aluminum catch, which is also painted in the color of the box. Also, it is possible to use a restrictor, allowing the gentle and noiseless closure of the end-slat to the box. The system is very practical, especially that it uses, to the maximum extent, other insect screen system components that are offered by ARKA.
