What is surprising? A thousand years later... and we still have doors swinging off hinges with latches and locks and handles in same time-worn positions! There are other ways to close-off an entrance (I'm partial to doors which slide into their own recesses), but the swinging door is overwhelmingly popular. Most doors are special-purpose. Irising doors or airhatch doors or rotating doors are very limited in use and take a bit of mechanical know-how to set up. Anybody can build a swinging door and hang it on hinges... although getting it hung straight is another matter. ;^) Looks good! Carolly
