Universal Shielding Corp. (USC) was established in 1972 and during this time span has provided in excess of 40,000 pre-fabricated modular RF shielded enclosures to Government, Military, Commercial and Medical facilities. USC is proud to be the only company in the industry to have maintained its original ownership since its inception.

Copper Screen Enclosures are designed to eliminate ambient EMI/RFI inside and contain RF signals from interfering with systems outside.
USC designs, manufactures, installs, and tests its RF shielded enclosures nationally and internationally.
USC's reliability, scope and quality of their services have earned them a well deserved reputation.
Both USC-26 and USC-44 series panels are interconnected with a framing system to form the enclosure.
Enclosures are completely erected from the interior and thus can be placed in proximity to parent room walls.
Can be dismantled, transported, re-erected, and still maintain their attenuation capabilities.
Parts are all numbered to enable customer to install chamber rapidly.

The USC-44 shielding system employs the same framing structure as the USC-26. However, the upper portion of the enclosure consists of a double layer of copper screen panels instead of solid panels.

This construction has the following advantages:

Facilitates communication between the interior and exterior of the enclosure

Dedicated ventilation is not required

Visual observation of testing is possible from the exterior of the enclosure

Eliminates sense of confinement for the engineer

VISUAL observations of testing are possible from exterior of enclosure.

Upper vertical wall panels and ceiling are copper screen panels.

In most cases fire protection sprinklers above the enclosure meet local fire codes.

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:

Model RCM-154 Door design encompasses:

Single Knife Edge (100dB to 10GHz)
Concealed finger stock - This design results in a damage free closure seal
Three point latch system
Three adjustable hinges

These are maximum values with optional components

Shielding effectiveness values are expressed in logarithmic, not linear, terms. Therefore, 80 dB of shielding effectiveness is not double the 40 dB level, but 100 times greater. Another way to express effectiveness is attenuation ratio, which compares the attenuation signal strength outside and inside the shield as shown below.

Shielding Effectiveness (dB)	Attenuation Ratio		Percent Attenuation

40		100 : 1		99.0
