There are different types of manual window opening systems. They all require some kind of physical effort from the user to operate the window instead of the use of electricity.

The system components can be simplified down to an operator, and an opener.

• The operator on folding and screwjack mechanisms is either a handle or a pole. Winding gear systems will use a remote handle which connects to the opener with a cable inside a conduit.
• The opener will be mounted at the window and either pushes the window open by using a chain or extends a threaded rod.
