Introduction
A crank out window is a popular window style commonly used in residential homes, especially in North America. Known for its ease of operation and excellent ventilation, this type of window opens outward using a hand crank mechanism.
If you’re considering new windows for your home, understanding how crank out windows work—and whether they are right for your project—is essential.
What Is a Crank Out Window?
A crank out window is a type of window that opens outward with the help of a rotating handle (crank). Instead of sliding or pushing, you simply turn the handle to open or close the window.
It is most commonly associated with:
- Casement windows
- Awning windows

How Does a Crank Out Window Work?
The window is connected to a mechanical operator system. When you turn the crank:
- The window sash opens outward
- The angle can be adjusted easily
- It locks tightly when closed
This mechanism provides better sealing compared to sliding windows.
Pros of Crank Out Windows
1. Easy Operation
Crank out windows are very easy to use, even in hard-to-reach areas like above kitchen sinks.
2. Excellent Ventilation
Because the window opens outward fully, it can capture and direct airflow into your home.
3. Better Energy Efficiency
These windows create a tighter seal when closed, reducing air leakage.

Crank out windows are often used in contemporary designs with clean lines and large glass panels.
Cons of Crank Out Windows
1. Mechanical Parts Can Wear Out
The crank mechanism may require maintenance or replacement over time.
2. Limited Use in Tight Spaces
Since the window opens outward, it may not be suitable for areas facing walkways or obstacles.
3. Slightly Higher Cost
Compared to simple sliding windows, crank out windows can be more expensive due to their hardware system.
