Ray-Bar Lead Lined Telescopic View Windows are manufactured for ease of installation in rough opening after wallboard is installed, with over 30 sizes “good in stock”. Designed for use in medical applications, it achieves a minimum lead equivalency of 1/16" (1.6mm), with X-Ray Protective Lead Glass factory pre-assembled into each of the Lead Lined Telescopic View Windows we sell. Standard frame construction is 16 gauge galvanized steel Jetkote/Paint lock.
Other available options of frame material are: hot dipped galvanized steel, powder-coated steel, stainless steel, aluminum, or anodized aluminum.
All of Ray-Bar’s X-Ray Lead Glass products are available factory set into these frames prior to shipment. All standard sizes are "ready to ship" in just 2 to 3 days. Custom sizes, frame profiles and material options are available in only 10 working days.
Ray-Bar proprietary lead lined telescopic view window frames are fabricated from 16 gauge Jetkote/Paint Lock material providing a rust resistant, paint ready surface, with 1/16" (4#) lead lining standard. Higher shielding value ratings are available upon request.
- Standard Ray-Bar X-Ray Lead Glass is 5/16" thick, providing 2.0 mm (5#) lead equivalent of shielding value.
- Ray-Bar X-Ray Safety Glass is available upon request, labeled to meet impact resistance ANSI Z97.1 and CPSC 16 CFR 1201 Cat 2 and is required in any window within 24" of any door opening, per glazing safety codes and regulations. All x-ray windows should be located at least 38" above finish floor (or more), and utilized in interior applications only.
- Please note: x-ray lead glass cannot be tempered as it is physically impossible due to its low melting temperature and surface characteristics. It will not survive the thermal tempering process or accept a chemical salt bath regardless of manufacturer; however x-ray lead glass is not required by any safety code to be "tempered". The good news is Ray-Bar X-Ray Safety Glass meets all current glass safety codes for impact resistance and is permanently labeled accordingly per ANSI Z97.1 and CPSC 16 CFR 1201 Cat 2 and IBC 2406 requirements for hazardous locations indoors, which is particularly applicable in a medical facility environment.

Special Frame Options
All frame options listed below are available independently or in custom combinations with any of the listed options.
Our standard lead lined telescopic frames are ordered by actual glass size and fit into rough opening of 1" larger than glass size to allow 1/2" clearance around perimeter of the frame. The outside dimensions of our standard frame are 3" larger than glass size on x-ray side and 4-1/2" larger than glass size on control side.
Example: A 12" X 12" telescopic frame will fit into a rough opening of 13 " X 13 " and will have an outside dimension of 15" on x-ray side and 16-1/4" outside dimension on control side.
Please note: Dimensions vary for telescopic view window frames with special options.
Remove slip side of telescopic view window frame and install lead lined/lead glass portion on x-ray source side of rough opening. Install "Slip-Side" flange on control side of rough opening at same time and slide both pieces together tight to wall. Check to verify that frame is level and fasten with self-tapping pan head screws on flat flange portion. Always screw through both halves of frame, 6" on center (4 places minimum).
Specialty Color and Finish Options
Many specialty options are available for our window frame finishes including: Aluminum, stainless steel, "Alumicoat" powder coat, any solid color powder coat and multiple wood grain finishes

Ray-Bar PET/CT/MRI Shielded Window Assembly
Ray Bar’s Multi-Shielded Medical Imaging Control Window is for new or retro-fit applications in PET/MRI, PET/MMR or CT/MRI dual imaging modality rooms. These rooms require a radiation protective aspect for shielding against x-ray gamma radiation during Positron Emission Tomography (PET Scan) or Computerized Tomography (CT Scan) imaging procedures while also shielding against electro-magnetic and radio frequency spectrum energy fields for the Magnetic Resonance Imaging (MRI) procedures. This window assembly is available as a complete new modular unit or as a retro-fit shielded "cover" to fit over an existing control window assembly, and is an excellent choice overall for protecting either medical personnel and / or sensitive electronic equipment from harm, crosstalk or interference from electro-magnetism or radiation exposure depending upon your projects unique design.
Medical X-Ray Radiographic Diagnostic Imaging Control View Window Design Requirements
NCRP #49 requires under Radiographic Installations 5.3.2: "Provision shall be made for the operator to observe and communicate with the patient from a shielded position at the control panel. When an observation window is provided, it shall have a lead equivalence at least equal to that required of the partition (or the door) in which it is located."
The current AIA and FGI Guidelines for Design and Construction of Health Care Facilities requires under Shielded Control Alcoves 22.214.171.124: "Each x-ray room shall include a shielded control alcove. This area shall be provided with a view window designed to provide full view of the examination table and the patient at all times, including full view of the patient when the table is in the tilt position or the chest x-ray is in use."
NCRP #147 requires under Types of Medical X-Ray Imaging Facilities, Radiographic Installations 2.2.1: "The control booth shall have a control window or viewing device that allows the operator to view the patient during all x-ray exposures performed in the room. The operator must be able to view the wall bucky and x-ray table, as well as patients confined to stretchers. When an observation window is used, the window and frame shall provide the necessary attenuation required to reduce the air kerma to the shielding design goal. The window(s) should be at least 45 x 45cm (18" x 18") and centered 1.5m (60") above the finished floor."
* Please note the above uses of the word "shall" is a requirement, and use of the word "should" is a recommendation.
DOA Technical Manual TM 5-805-12 and DOD Unified Facilities Criteria UFC 3-190-03A "X-Ray Shielding" both state: "Leaded Glass: The leaded glass is a clear lead glass sheet approximately 1/4" inch thick and is installed in single or multiple thicknesses to provide a lead equivalent not less than that of the partition or door of which it is a part of".
ICRP Publication#44 "Protection of the Patient in Radiation Therapy"(33): "There must be a means for observing the patient continuously during treatment. This may be accomplished by use of a lead-glass window,"
IAEA Chapter 16 "Radiation Protection and Safety in Radiotherapy" 16.10: "Adequate systems, devices or other means should be provided to allow operator to have a clear and full view of the patient. The systems for patient observation should be redundant and independent (e.g. closed circuit television or lead windows, depending on type of treatment unit)".
*Please Note these important considerations:
All television or electronic camera systems require skilled maintenance and service, and have the potential of failing, having picture loss and component problems. An x-ray lead glass control window provides a continuous view of patient, equipment and room, and has no maintenance other than occasional cleaning.
Additional Safety Design Consideration
Per ANSI Z.97.1 and CPSC 16 CFR 1201 Category 2 standards, any x-ray control window occurring within 24" of a door opening, or any vision lite window occurring in a shielded door must have impact resistant X-Ray Safety Glass, and be permanently labeled as meeting these required impact resistant standards.
Please Note: X-Ray Lead Glass cannot be tempered as it is physically impossible due to its low melting temperature and surface characteristics as it will not survive the thermal tempering process or accept a chemical salt bath regardless of the manufacturer; however X-Ray Lead Glass is NOT REQUIRED by any safety code to be "tempered". The good news is Ray-Bar X-Ray Safety Glass meets all current glass safety codes for impact resistance and is permanently labeled accordingly as per ANSI Z97.1 and CPSC 16 CFR 1201 Cat 2 and IBC 2406 requirements for hazardous locations indoors and this is particularly applicable in a medical facility environment.
