1. Window Size and Weight:Consider the size and weight of your casement window when selecting an operator. Larger or heavier windows may require a dual-arm operator for optimal performance, while smaller windows may be better suited to a single-arm operator.

2. Window Style:The style of your casement window will also play a role in determining the best operator for your needs. For example, if you have an awning window, you'll need an awning operator designed specifically for that type of window.

3. Aesthetics:Consider the appearance of the operator and how it will fit in with your home's décor. Prime-Line offers a range of finishes and handle styles to ensure you can find the perfect match for your aesthetic preferences.

They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
