Our shutters have a variety of design options to suit any window. The main consideration is whether to mount the shutter within the recess or outside the window. If using a complete frame design, the Small L Frame is most suitable for a recess fit shutter as it's the slimmest available. To ensure the shutter sits within the recess without the frame protruding out of the window frame, a depth of 65mm is required from the window or any window hardware like a winder.
If your recess depth is less than 65mm, then a face fit mount is the best mounting method with a Medium L Frame. As the shutter is mounted outside of the window recess, the shutter blades move freely within the frame and obstructions are not an issue.
