How Crank Open Windows Work

Operation and Mechanism
You want windows that open easily and give you control over airflow. Crank open windows make this possible. You turn a handle at the bottom of the frame. This handle connects to a movable arm. When you turn the crank, the window sash swings outward on side hinges. You can open the window as much or as little as you want. This design lets you enjoy fresh air from top to bottom. Unlike sliding windows, you do not have to push or pull the glass. You get smooth movement every time.
Tip: Crank open windows let you catch breezes from any direction. You can angle the sash to direct airflow into your room.
Casement windows stand out because they use a crank instead of a sliding track. Sliding windows need more effort to open and close. They also do not give you as much ventilation. With a crank, you get full control and better airflow.
