Rated 4.4 out of 5 by 52 reviewers.
Rated 5.0 out of 5.0 by great door, excellent value Great looking door. Very well built. We had it professionally installed as we had to have the entire frame redone. They were very quick and it looks great. I would recommend this door to a budget minded family with security in mind. June 24, 2013
Rated 1.0 out of 5.0 by Shattered Glass Purchased this door a little less then 2 years ago. We were sitting eating dinner yesterday and heard a air build up then pop door glass shattered when nothing hit it. Had to go through door manufacture to replace glass and they are very rude and refuse to replace the glass as they say glass is not under warranty. September 25, 2015
Rated 5.0 out of 5.0 by attractive & sturdy Bought the black door for dad's home. Easy installation, sturdy and attractive. Received many compliments from neighbors. Be sure new door knobs and locks do not interfere with existing door knobs and locks. Check depth between the two doors and their locks before purchasing your new hardware. June 3, 2014
Rated 4.0 out of 5.0 by Storm Door Purchase We love our door, and it looks good on the front door of my house. I would recommend this item to others. August 11, 2015
Rated 5.0 out of 5.0 by Highly recommended. I am very pleased with this door. I had the experts to install the door and it looks great. Security was an issue and I must say I have the security I was looking for in this door.The rails are iron and not metal. November 27, 2012
Rated 5.0 out of 5.0 by Nice Door The door doesn't use normal hardware like other security doors. Had to buy a Kwik set with separate door handle and deadbolt at around $75. Other than that, the door is very solid and closes nicely with authority With my old one I never knew if it would close or not. Also with the glass in the middle, the closer will be above or below the middle of the door so if you have a previous closer in the middle, you'll have to repair the old holes. March 31, 2015
Rated 5.0 out of 5.0 by grisham security door Got one about 15 years ago. Had some problems with the handle coming off until I drilled it and put a pin in it. Many years later the bronze bushings in the hinge wore out and cost about $50 to order a new hinge. Overall I'm satisfied with it and will buy another one soon. I haven't seen much competition or many to choose from but this one is worth the price. June 30, 2010
Rated 5.0 out of 5.0 by great security door! We purchase this door over two years ago. We didn't have any installation problems as we had it installed by the expert. Has added much security to my home. I will be purchasing another one for my back door! I would definitely recommend this door! January 14, 2012
