Heavy duty steel flush security unit with welded frame. Complete with a commercial grade lever entrance lockset, single cylinder deadbolt and spring hinges in a satin chrome finish. Equipped with a 90 minute fire and smoke label. Manufactured with the highest quality Galvanneal steel that is satin smooth to the touch and ready to receive premium latex or oil based paint once cleaned. Even though it looks like raw steel it is not. The Priming process is done at the Steel Mill when the steel is being manufactured.

The Frame is made for a wall thickness of 4-7/8 in. and used primarily in new masonry or drywall construction when the wall is being built.

Rated 5.0 out of 5.0 by Great product...great price! I installed this door one Saturday in a concrete block wall for a bad weather safe room in the basement. It worked out just as planned. It all fit square and plumb and as an added bonus, it has all of the door hardware included! I would recommend this unit to anyone needing a security door. February 8, 2014
Rated 5.0 out of 5.0 by Steel door purchase haven't installed the door as of yet, but very pleased with ordering, delivery and product itself April 8, 2015
Rated 5.0 out of 5.0 by 36"x80" Flush Gray Metal exterior door. I ordered this door on-line. Took a couple of weeks to get the door in so that it could be installed. The door was exactly what I ordered. The door came in as expected and everything was included with door that was specified when order was placed. The door was a breeze to install and works great. I would recommend this door to anyone needing a fire proof door or a steel door for an installation in an out building. I purchased a metal door beacuse I wanted something a little stronger than a wood door intalled in a wood frame.Home Depot is a great company to work with!!. April 23, 2013
Rated 5.0 out of 5.0 by quality built This door is built very well . Adds security to storage building May 14, 2013
Rated 4.0 out of 5.0 by great door for the price... This door installed pretty easily and seems very solid as a commercial door. The only thing I didn't like was the finish. It looks like a nice and even grey finish but it was actually really rough and galvanized looking. So bad it needed to be painted grey instead of just left alone as I had planned to. Overall good door and client was happy, just plan to paint if you purchase. October 21, 2014
Rated 4.0 out of 5.0 by overall a good door Easy to install door, looks great .One issue is the hinge supports could have had better fit. Also my deadbolt that came with the door went bad after one month ,the key could not be taken out ,so I just replaced it. March 18, 2014
Rated 4.0 out of 5.0 by nice looking door great door when fire rated doors are called for. Good price as well. October 25, 2011
