Roller blinds are a type of window covering made from a single layer of fabric that wraps around a plastic or metal roller positioned at the top of the window recess. They are operated by a sidewinder chain or string on either side of the blind. Pulling the chain in one direction raises the roller, while pulling it the other way lowers it. Additionally, Blinds Unlimited offers an automatic motorized mechanism that allows for effortless control with a single touch of a remote.
