<p>The site mounted or prefabricated blind has a roller shaft (1) supported at its ends by two parallel brackets (2). A pin (6) fits into an opening in the profile (3), to support the bracket. The profile also has a U-section groove (4), that acts as a guide rail. A hinge (7) connecting the pins and brackets has a rotational axis, orthogonal to the roller shaft axis, so that the pins can be parallel to the shaft during packing and can be angled to suit the line of the profiles already placed on site.</p> |
