This is a pre-hung explosion resistant blast door that offers excellent protection from the extremely high pressure blast waves like those produced by a large conventional or nuclear device detonated in relatively close proximity.

This is not a blast hatch - it mounts in the vertical position - like a normal door. You can step over the threshold and walk through it. We also have a blast hatch that is built similar to this door. A blast hatch is a smaller "door" that mounts horizontally like a hatch on a submarine. Please below for more information about this hatch.

The ASR series 7200 sealed blast doors are rated to withstand high pressure waves up to 7,200 pounds per square foot - that is 50 pounds per square inch (PSI). Additionally, this door also offer an air tight compression seal between the door and the frame allowing for the use of a positive pressure NBC filtration system inside the shelter.

All the seemingly small, but very important details are engineered into this door:

• The handle comes off and you take it inside with you so there is no "pick point" for someone to try and attach a tow chain or use a pry bar to to gain access when you are inside.
• When not in use, a steel shroud covers a user-supplied paddle lock in order to ensure nobody enters your shelter without your knowledge. A key component of this hasp is also taken inside with you in order to keep someone from easily placing a lock on it while you are inside.
• The door is constructed of steel - but after you hang it in place, you fill it with concrete - it is ready to fill, no forms necessary. This construction method does a few very unique things - it keeps the door relatively light while installing, it has a lot of dense mass between you and whatever fallout is outside your shelter after the concrete is poured, and it helps to prevent anyone from using a cutting torch to gain access through the door - concrete doesn't "burn."
