Separate the cords from the roll according to the number of measuring rods.
Insert one end of a pre-cut cord through the smaller hole of the fixation cap on one side of the measuring rod and tie a large knot so that it stops in the larger hole.
Thread the other end of the cord through the roller bracket, lower it to the opposite end of the measuring rod, and secure it in the same way.
Fold the cord in half between the fixation points and thread it through the second roller bracket.
Thread the folded cord through the fixation caps, lift the measuring rod to the ceiling, and secure the first height level. Adjust the second height level to a comfortable user height.
