2.1 TECHNICAL DATA

Due to the concave shape of the slats, it might cause uneven stacking of the blind. Also the
fabric loops or ladder cords can end up between the slats. The end bead is horizontal, yet it
seems as if the slats are running at an angle. Once the blind is completely taken up, this will
no longer be visible, as the blind disappears in the box. The functioning of the Venetian blind
is not impaired by this.
Technical details of our Venetian blinds can be found in our current Product Handbooks at our
distributors.
