Our stacker security doors went in today for the downstairs kitchen area. We have 5 sets of these doors throughout the house and will be getting the rest after Christmas. What a joy they are...we can just keep the doors open throughout the day keeping flies out as well as offering security. At first I was concerned they would ruin the look of the home both from inside and out but they just blend so easily you don't even notice them. The photos below show how they look both from the interior and exterior.
