You can adjust where your roller shade stops and the speed at which it roles down or up with the wheels on the side of the roller shades. While your roller shade is installed, if you reach up to the right, you will encounter the clear stop adjustment wheels. This adjustment allows you to change the height at which your shade will stop when it rolls up. On the left is the speed adjustment wheel(s). Turning these will change the speed at which the shade rolls up. Turning the shade clockwise will allow the shade to roll up quicker, and counter clockwise will increase the tension allowing a slower roll of the shade.
