Radio Frequency Shielding Doors
Krieger's radio frequency doors are used in installations where TEMPEST standards are required, or where there exists a need for a radio frequency barrier for high frequency shielding.
Radio Frequency Shield
≥ 60dB of shielding effectiveness in the electric, planewave, and microwave fields in the frequency range of 1 KHz to 18 GHz.

Magnetic field shielding performance meets the requirements of NSA 73-2A (1 kHz, 10dB; 10 kHz, 20 dB, 100 kHz, 30dB, and 1 MHz, 40dB).

ADA Compliant
Krieger's radio frequency doors meet the ADA threshold requirements of 1/2 inch without portable ramps, allowing them to be used in any location.
Single, or pairs of, hinged doors, in standard and custom sizes, manual or power operated. Assemblies can be tied into any type of shielding construction.

Krieger offers standard frame designs and can engineer special frame profiles to complement wall construction and architectural style.

Standard and custom TEMPEST door sizes available. No limits.
Robust Seal
Krieger's unique radio frequency seal does not use a knifed edge found in other radio frequency doors, rather it is similar to robust weather stripping, dramatically increasing the door life while reducing maintenance costs.
Performance Combinations
KriegerShield radio frequency doors can be manufactured for multiple performance requirements including acoustical, bullet resistance, blast resistance, thermal barrier or any combination thereof.
Available in all standard builders' hardware materials and finishes. Latch and lock sets, panic devices, security and power operating hardware is also available. Radial bearing, cam lift hinges are available.
We can match any finish or create a custom look. Your options are endless.

Wood veneer interior Radio Frequency doors may be finish-sanded, primed, sealed with conversion synthetic sealer or completely prefinished prior to shipping.

Stainless steel finishes can be embossed, patterned, etched, bead blasted and colored. Bronze, brass, copper, and plastic laminate finishes are also available.
