Lever handles are mechanical devices used to operate doors, gates, or other equipment. They consist of a long arm that pivots around a fixed point, allowing users to apply force with minimal effort. When pushed down or pulled up, the lever handle engages a latch or lock mechanism, enabling the door to open or close. These handles come in various designs and materials, including metal and plastic, to suit different styles and functions. Lever handles are often preferred for their ease of use, especially for individuals with limited hand strength, making them a popular choice in both residential and commercial settings.
