The Shield Fortress Series is designed to help create a secure environment for locations with extremely high threat profiles or security challenges. It has been tested at NTS Chesapeake in Belcamp, MD and at Intertek in York, PA to the US State Department (DoS) forced entry standard SD-STD.01.01 Rev. G at the 15 minute level (FE15), ASTM F3038 15 minute, the UL752 ballistic standard (level 3 and 8), and the National Institute of Justice (NIJ) ballistic standard 0101.06 levels III and IIIA. It has also been tested and certified at the iFT Rosenheim laboratory in Germany at the resistance class 4 (RC4) rating according to EN1627.

Our highly specialized manufacturing process makes us the best choice for door restoration and reproduction projects. We design our doors for both interior and exterior applications in residential and commercial properties. We can easily match the design of other doors on your property to ensure that the only person who knows about your security door or window is…you.

You don’t compromise on style; we never compromise on security. It’s military-grade security at your door.

About the Shield Fortress Series High-Security Door

Our top-of-the-line forced entry-resistant door is custom designed for locations at very high risk of burglary or forced entry (bullet-resistant upgrade options available).

 Special Features

Fortress Series FE15

One of our core beliefs is that the secret to good security is to keep it a secret. That’s because security is much harder to defeat when you can’t see it and don’t know what you’re up against. Our custom made high-security doors and windows can be designed to look like just about anything, including unique wood stains, 3D millings, and custom shaped glass.

The Essential Details of the Fortress Series Forced Entry Resistant Door
  1. Armored multi-point locking system encased in drill-resistant manganese.
  2. Optional motorized lock with a biometric fingerprint scanner, keypad, card reader, or integration with a 3rd party access control system.
  3. High-security Mul-T-Lock keys and cylinders.
  4. Adjustable security hinges that make even the heaviest doors easy and comfortable to operate.
  5. 3-½” thick door and 4-½” wide frame.
  6. 2” thick layer of rockwool and double gasketing for outstanding sound and heat insulation.
  7. A virtually unlimited range of architectural designs, natural hardwood or engineered wood door skins, raised panels, millings, glazings, and colors that allow us to create highly secure and beautiful doors.

mtl-mt5Mul-T-Lock Cylinders

Mul-T-Lock’s MT5+ cylinders are a natural fit in our doors. Mul-T-Lock keys cannot be copied and even the installer’s green key is automatically deactivated when the homeowner starts using the yellow key. A master red key deactivates all others if any yellow keys are lost or stolen, providing the ultimate in security and key control.

 

 

flamFIAM X1R Electromechanical Lock

The Fiam X1R electromechanical locking system is the most sophisticated and secure electronic lock on the market. Locking in three directions with up to 20 bolts, the X1R can be integrated with keypads, biometrics, card readers, or any other access control system. Never again will you ask yourself “did I lock the door?” because the X1R ensures that your door is always secured.

 

 

Mottura 85/87 Series Mechanical Lock

The Mottura 85 and 87 series armored mechanical multi-point locks are the most robust and durable mechanical locking solutions in the world. They secure the door in three directions with up to 20 bolts and have a unique patented design that protects the key cylinder from attack.

 

 

 

 

 

ekey Biometric scanner

Fingerprint scanners offer the ultimate in biometric security. They are convenient, affordable, safe, and reliable. The scanner analyses each fingerprint swipe to provide a unique thermal signature and a special code to open the door. Up to 99 different fingerprints can be stored, and adding or removing authorised fingerprints is easy.

Door Layouts

KEY DETAIL OPTIONS
  • Transom: non-operable window above a door
  • Sidelite: non-operable window beside a door
  • Arched door: door curved at the top
  • Arched transom: curved window above a door

Test & Certifications

How We Test Our Doors

  • 4.5 man-hours of attack time
  • Six man team spends 15 minutes attacking the center of the door, 15 minutes on the lock side, 15 minutes on the hinge side
  • Expanded list of tools used including sledgehammers, crowbars, axes, battering ram, wedges, propane torch, bolt cutters, and hacksaw
  • UL752 level 3 and level 8 bullet resistant (optional)

Additional Testing Details

The Shield Fortress Series was tested at NTS Chesapeake in Belcamp, MD, and Intertek in York, PA, to the US State Department (DoS) forced entry standard and ASTM F3038-14 at the 15-minute level (FE 15) and at the Kaunas University of Technology, achieving a resistance class 4 (RC 4) rating under EN1627. This certifies that the Shield Fortress Series can withstand entry from highly skilled attackers using heavy-duty tools such as crowbars, sledgehammers, axes, wedges, saws, steel-cutting pliers, and power drills. The Fortress Series was also tested for bullet resistance to UL752 levels 3 and 8, NIJ levels III and IIIA, and European standard EN1522 levels FB4 and FB6. The door is suitable for government offices, commercial buildings, private homes, and apartments.

Door Ratings Matter
What level of protection does the Shield Fortress Series offer?

  • FE15 rating under SD-STD.01.01 Rev. G (US State Department)
  • FE15 rating under ASTM F3038-14 (American Society for Testing and Materials)
  • RC4 (Resistance Class 4) rating under European Standard EN 1627
  • UL level 3 or 8 bullet-resistant (optional)
  • NIJ level III or IIIA bullet-resistant (optional)

They are designed with high ventilation capacity. The dampers can protect people and equipment from explosions or momentary pressure change (e.g. tornadoes, etc.). When an explosion occurs, the valve will close instantly under the action of the shock wave; when the shock wave disappears, the valve will be automatically restored. They are mainly used in refineries, oil & gas, nuclear power plants and some other facilities which are at risk of explosions. They are installed on the air openings (air inlet and air outlet) of the facilities.

Expansion Chambers RK

Expansion chambers RK type are used to reduce the blast wave pressure after the blast dampers. Our range includes three types of metal expansion chambers: RK-0.5 (volume 0.5 m3); RK-2-I (volume 2 m3, air inlet from the side) RK-2-II (volume 2 m3, air inlet from the top). On request, it is possible to manufacture the RCF-6 product with built-in prefilters.
Other spaces can be used as expansion chambers – reinforced concrete rooms, sections of the air duct, and other.
