The design of folding openers is tightly coupled with the measurements of the frame profile on the window. This regularly means that a custom design is required to ensure good opening and secure closing of the window is possible.

Use the button below to fill in a form with as many details as possible and we’ll get back to you with the available options. If we find a standard folding opener will not work for your frame, we can work directly with the manufacturer to create a custom version that will work with your dimensions. You can find out more on our dedicated folding opener page, including a handy Specification Sheet to assist you with the information we’ll need.
