Mr. Molituzen suffered a break-in through a back window, and wanted to put shutters over it. We had to talk him out of adding spikes.
Since Mr. Molituzen didn’t want swinging panels sticking out when the shutters are open, we designed a vertically sliding window shutter. We mounted a pair of tracks on either side of the window frame, with sealed bottoms to keep the window shutter from falling out. The tracks have multiple holes along their lengths so Mr. Molituzen can turn out the built-in pegs and lock the window shutters at any height.
