It is, its the larger size of their doors. The room is a concrete and rebar "storm room" in the basement so I needed a door that allowed the gun vault to double as a storm room door. I wanted in swing and ability to open from inside the room once locked, this met those things. I do wish it was fire rated however I took inside panel off and put some fire rated durock inside to help alittle. This concrete room is off the main foot print of house so in event of fire there is hope it would be better than a room in middle of the basement.
The door fit right in my concrete opening, youll need two guys. I ditched the lag bolts they sent with door as they are for installing in wood frame. I used red head concrete anchors in sides and top. All in all I like the door, easy to operate, zero problems so far with the electronic key pad and it has a key over ride in event the electronics go down. Ease of use for my wife and kids in event of storm or intruder is good.
Yes there are many vault doors that are better, but for the price point and options it fit the bill. Was also nice that I ordered thru home depot, it was delivered to my local store for free and they loaded it into my truck for me.
Hollar if you have other questions about door
