Shutter doors are MULTISQUARE, meaning all adjacent shutter doors will also open/close. They also have really bad damage resistance. Still, they’re the only multisquare and opaque door part. This makes them a good choice for back/trunk door of a crafting rig, so that you can close them all at once and not get bothered by zeds.[/quote]Personally I think heavy duty hatches should also block sight.
