The revolutionary SmartCord® operating system uses a short retractable cord mechanism. With one stroke of the cord the blind lowers completely, or stops when you pull again. It always retracts back to the same length, which means increased safety for children and pets. A slim design of the rails makes the product applicable to almost all window forms and shapes. - For young children difficult to reach, complies with the European standard EN13120; - No long operating cords on the floor; - No hazardous loops; - Profile merges with window; - Easy to use.
