A manual window opener works like a chain actuator but is moved by hand. A handwheel or crank pushes the chain out and opens the sash.
When is it the right choice?
When there is no power connection, ventilation is only occasional or a low-cost solution for transoms is needed.
- No electrical installation needed
- Can later be upgraded to an electric actuator
- Examples: VS-MKA, VS-MKA2
