A Long Spindle is an extended metal rod used in door and window hardware to connect handles or knobs on opposite sides of the fixture. Spanning through the door or window mechanism, it ensures that both sides of the handle work in sync, allowing for smooth operation of latches or locking systems. Long spindles are especially useful for thicker doors or where additional reach is required to connect the handles effectively. They come in various lengths and can be cut to size for a precise fit. Durable and versatile, long spindles are an essential component for secure, functional door or window hardware.
