What are the wide range of uses for hardware door and window pulleys

Window and door pulley, also known as window and door track pulley, is a new type of sliding accessory for windows and doors, and its function is mainly used to save energy. 

The main function of door and window pulleys is to enable doors and windows to reciprocate along the track under the action of external forces by bearing the mass of the door and window fan. This feature makes the opening and closing of doors and windows much easier, greatly saving the user's strength.

In addition, the pulley not only plays a role in daily use, but also has a certain protective effect on doors and windows. For example, the fixed pulley can change the direction of force, so that the force used to lift heavy objects are equal, thus reducing the pressure on windows and doors. Therefore, the extensive use of window and door pulleys is not only reflected in the convenience of people's daily life, but also in the protection and maintenance of the service life of windows and doors.
