A security storm door is an attractive alternative to big steel doors. Other members of my family have used them very successfully. See link below. I don't know if these are the same ones they use but they look similar. Make sure you get one that has a bolt that extends on both sided of the door! Not just the door handle side but ALSO the hinge side. These are more expensive and more difficult to install but well worth it. A huge bolt lock will not help if the hinges come off the frame.<br><br>In my NYC apt. I am in a high rise so the risk of window entry is nullified but we do use Steel door frames. Considerably more secure than wood! Of course I also have a doorman that won't let anyone past his bat - lol.<br><br><br>http://secure.ashoppingcart.com/robsecure/eshop/10browse.asp?category=security+door<br>
