Ray-Bar Lead Lined Access Panels


Ceiling Access Panel

Ray-Bar Shielded Access Panels are for maintenance access in shielded walls, partitions and ceilings. These units are internally lead lined for radiation protection in medical centers and hospital imaging room installations. They can also be used in remodels to safely access and service utilities. Access Door and Frameare fabricated from 16 gage galvannealed steel with a "ready to paint" prime coat.

Lead lining available in 1/64" (1#), 1/32" (2#), 1/16" (4#), 3/32"(6#) and 1/8"(8#) standard thicknesses to meet the shielding requirement in the wall, partition or ceiling that the access is required.

Higher lead protection thicknesses are available upon request.

Important Notes and Information:
*Our Single gang 2" x 4" or a "4-S" Double gang electrical 4" x 4" box knock-outs will accept 1/2" and 3/4" conduit
*These products are all available in 13 standard lead thicknesses.
*Lead surface is coated to reduce any potential lead contact exposure.
*Protective gloves should be worn during installation as extra precaution.
We always recommend that the customer first confirms the actual lead thickness shielding requirements in all the walls, and then actually order the maximum thickness shielded wall lead for all the boxes to eliminate the possibility of a lesser lead shielded box to be installed in a higher shielded wall in the field and potentially creating a radiation leak.
Our quotes include all crating,boxing and freight to ship to your location.
Fabrication time is typically only 2 to 3 business days after placement of order.

Ray-Bar Shielded HVAC Diffusers

Lead Free Shielded HVAC Diffuser

Ray-Bar Shielded HVAC Diffusers are available exclusively from Ray-Bar in a variety of sizes and configurations to meet your air volume (CFM) and shielding requirements.
Ray-Bar Shielded Diffusers do not contain any internal lead lining.
Ray-Bar radiation shielding methods,materials and designs are proprietary and unique on these HVAC units.
When properly installed this eliminates the need for additional lead shielding/backing behind the ducts as the diffuser provides the necessary shielding equivalency and is overlapped as self-sealing into a lead backed drywall ceiling.
This is a particular advantage for ease of adding duct penetrations as retro-fit into an existing lead shielded wall or ceiling.
They are also available to meet low noise requirements and high security designs.
For an accurate quote on this product please provide this important 7 items of informtion:
*Shielding Level Requirement per your shielding report
*Diffuser duct size
*Square or Round Duct (adapter)
*CFM requirement
*Supply or Return
*Powder Coat Color (Or Stainless Steel)
