RF Shielded Doors


Universal enclosures provide extraordinary shielding attenuation.

This is attributed to the shielded enclosure door design.


All Universal Shield Room Doors

Have a Minimum of Three Hinges

and Three Latches


Latching Mechanism

USC enclosure doors are equipped with a 3-point latching mechanism for tight, RFI-EMI-secure closing.

Bearing surfaces, rollers and door cams are of case-hardened tool steel, designed to provide years of trouble-free operation with no loss of attenuation capability due to friction and wear.

Our doors are extremely easy to operate; they require less than 20 pounds of force on the handle.

Door Construction

To achieve the attenuation levels required, our doors are equipped with a minimum of two rows of beryllium copper "fingers" around the periphery of the door.
In the closed position, the fingers contact the door frame to assure an RFI/EMI leak-proof seal. The following is a type of door/frame construction offered by USC
The shielded door manufactured is our Type RCM-154 utilizing a brass extrusion mounted on the periphery of the door frame.  The extrusion houses two (2) rows of "fingers" which are concealed from accidental damage. The door leaf has a brass "knife-edge" extrusion at the perimeter which mates with the fingers within the frame when the door is closed.  This design results in a damage-free closure seal with highly efficient prevention of RFI/EMI leakage. To meet environmental conditions all brass extrusions are nickel plated. The door assemblies provide attenuation meeting all requirements of NSA-94-106, NSA-65-6 and HEMP specification.
