The Outus double-chain window opener is a device that uses a dual-chain drive to open and close windows. It is typically used for large, heavy windows, skylights, or curtain wall windows. Compared to single-chain window openers, the double-chain design provides greater push and pull force and better stability, making the window operate more smoothly. This type of window opener is available in manual and electric versions. The electric version can be remotely controlled, automatically opened and closed, and can even be connected to smart home systems
