At the upper part, there is an aluminium shell, which encloses the transparent film or the fabric, which is driven vertically, manually or electrically, and rolls up in a cassette. At the lower part of the structure there is, in parallel with the axis, an aluminium counterweight in side drivers, which are made of aluminium, of 12 centimeters dimension, with a brush on the left and on the right to seal and insulate from the rain, the wind and the cold. The drop awning box mostly completes the pergola structure, covering the space perimetrically. Suitable for professional and domestic spaces, adding your space elegance and discreteness.
