Safe Room Doors

Steel ballistic door for a safe room

This is the safe room door that the cheap “vault door” outlets don’t want you to see

  • It features a steel envelope that you fill with concrete after the door is installed.
    A thousand pounds of c
    oncrete cannot be cut with a torch.
  • 7.62 NATO ball ammunition makes it about half way through the door panel.
  • The three rotating cam latches are slaved together and are operated by one lever.
  • Each of these massive latches are engineer certified to hold over 14,000 pounds. That means it will take TWENTY-TWO TONS of force to make the latches fail. This is way beyond what the cheap ornamental “vault” style doors will hold – no matter how many pins they claim to have. The thin sheet metal shroud holding the pins always fails first.
  • An encrypted electronic keypad on the outside is connected to a deadbolt mounted on a rotating hard plate on the inside.
  • This unique rotating hard plate allows for a mechanical release lever on the inside that ensures you will always be able to ex-filtrate your safe room!

Strength

This safe room door starts with our proven concrete filled blast door leaf. We’ve supplied these doors to the US military, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Space X, Blue Origin, and several American nuclear power plants. You can see some of these doors here.

We’ve had this door independently engineer certified to hold 50 PSI in the seated condition and 14.5 PSI in the unseated condition.

All true blast doors have the door leaf overlap the frame. This prevents the shock load from a nearby detonation from knocking the frame out of square and wedging the door into the frame. A vault style door that nests into the frame can trap you inside your safe room.

Our rotating cam latches engage the cam plates and draw the door leaf toward the frame, compressing a closed cell EPDM door seal. We have a calibrated spacer that gives a steel on steel stop to the door leaf so the door seals do not get over-compressed.

Security

This door features an electronic keypad on the outside that operates a deadbolt lock on the inside of the door. There is a wire that goes from the keypad to the deadbolt. The code to open the deadbolt is stored in firmware in the deadbolt box on the inside, not in the keypad.

The inside deadbolt box is mounted on a rotating hard plate that is offset from the outside keypad. Drilling out the small shaft the wire goes through will miss the inside deadbolt and all other internal mechanisms. This floating hard plate has a handle that allows you to rotated the deadbolt out of engagement with the lock bar. This is a mechanical release that prevents you from getting trapped inside your safe room due to electronic failure.

The cam plates cannot rotate unless the deadbolt retracts from a correct code entered into the keypad (from the outside) or the release handle is rotated (from the inside). 

The 3/4″ solid steel shaft that goes through the door and links the inside and outside cam handles. It is mounted in a machined steel barrel that has oil impregnated bronze bushings and a stainless steel grease fitting.

This shaft has a machined shear point that will break if a cheater bar is put on the outside handle to force it open. The shear point will snap before the deadbolt gives way. There is also a shoulder machined on the shaft that prevents punching out the remaining part of the shaft after it shears off.

Every little detail has been thought through to ensure your safe room door cannot be breached!

Threshold of a ballistic door

Inward swinging

This is an inward swinging safe room door in a gun room. It is anchored to the inside of the 12 inch thick concrete wall with engineered fasteners that are rated by the manufacturer for a total of over 60,000 pounds of pull-out force.

Threshold of a ballistic door

Outward swinging

This is an outward swinging safe room door in a gun room. It is anchored to the outside of the concrete wall with the same engineered fasteners.

It features wall capture brackets that attach to the frame and wrap around to the inside of the wall to keep the frame in place if the fasteners on the outside are attacked.

There is also an interlock on the inside of the door leaf that engages two lugs in the frame so if the massive hinges are cut off, the door leaf will stay in place on the frame.

The hall of shame

What happens when you do real world testing on the cheap ornamental doors that are called “vault” doors by online marketing outlets?

All those shiny pins get deflected and wrinkle up the thin sheet metal. It does not matter how many or how big the pins are, the usual mode of failure is the tinwork that is supposed to hold them in place. It fails and the door is breached.

These doors are assembled from imported parts that are spot-welded into ornamental doors with nice paint jobs and fancy placards. Then they are marketed as “vault” doors for your safe room.

The pins have no way of drawing the door into the frame to compress the seals. That’s why most of them use bulb seals – to fill the gap between the door leaf and frame.

Here are some common terms used in the ornamental “vault” door business:

  • “composite door” – sheet metal over plywood
  • “gypsum fireboard” or “fire rock” – drywall
  • “relockers” or “relocking devices” – spring loaded internal devices that lock you inside your safe room when the door is damaged
  • “step system door” – the door leaf is nested into the frame where it can trap you inside your safe room as a result of a nearby detonation or a malicious person prying on your door
