A Double End Pulley is a type of pulley system used for opening and closing curtains. The pulley is designed with two ends, which allows the cord or rope that controls the curtains to be attached at both ends. When the cord is pulled, the pulley helps guide the curtains smoothly and evenly along the track. The use of a double-end pulley provides added control and stability to the curtains, ensuring that they open and close smoothly and consistently. This type of pulley system is commonly used in commercial or theatrical settings, where curtains need to be opened and closed smoothly and efficiently. Double-end pulleys for curtains are easy to install and can be customized to fit the specific needs and requirements of each installation.
