The SCDGA Series Transmission Gear is the foundational drive component for inward-opening Plastic Steel Door and window systems. It translates the rotation of the handle into precise vertical movement across the sash height, engaging multiple locking points simultaneously to provide airtight seals and forced-entry resistance.

Part of the Luoqi Hardware professional range, this system supports sash heights from 400mm to 1600mm. For heights exceeding 1200mm, the system is calibrated to support four independent locking points, ensuring structural stability and pressure distribution in high-wind environments.
