Controls refer to the mechanisms that allow you to raise, lower, and tilt the blinds. Controls are usually cords or wands. You will be asked to specify which side the controls will be placed on. All 1 inch aluminum blinds come with wand control for the tilt, since the headrail size does not allow for a cord. There are optional systems available that make raising and lowering a heavy blind easier; see EasyRise, EasyUp, EasyGlide, Liftmaster.
