ABSTRACT:
Vertical venetian blind skyrail permitting lateral adjustments, provision of a number of spacers hanging at the lengthened foot bumpers over both side lids of the skyrail at their intersections with the skyrail sheath, so that the transverse length of the skyrail is extended. With coordinated receding of the locking position applied by rotary sleevings which are structured like rotary, helical mandrels, it is made possible adjust lengthwise the lateral length of the skyrail, so as to better accommodate inadequacy of the railing size thereby.
