The Tiltrak 1000 vertical system is available with RS (supplied as standard) or ST runners.
The main difference between them is the shape of their peg which determines the gap between the top edge of the louvres and the headrail. The RS runners’ peg is shorter, reducing the gap to only 6mm, and making Tiltrak 1000 Vertical Blinds that utilise RS runners more light control efficient.
The unique shape of the RS runners’ peg means that they can only be used in conjunction with the RS slat holders (see image below), whereas the ST runners are compatible with a wide range of standard slat holders.
