I’m looking at ordering the perfect fit shutters, however they would be for lower sections of sash windows. The problem is the windows have handles to push the bottom sash up. The nearest I have found on the internet that are similar to ours can be found halfway down the page of the website listed at the end. Would you be able to use a handle bridge/spacer to allow the shutter to fit around these? There are two on each window & as some are for a bay two windows would be over a smaller area, approx 400mm. I look forward to hearing from you. https://sgcglass.com/pvc-u-sliding-sash-windows/
