IRISS CAP-CT Rectangular IR Windows for Switchgear Inspection

Reduce the risk of arc-flash by performing thermal inspections without opening switch gear doors.

The IRISS CAP is a series of rectangular reinforced polymer ir windows.  CAP windows are available in a variety of sizes to meet your specific space and application needs.  These windows meet every UL and IEEE standard and are guaranteed for life.


The IRISS CAP-CT IR windows feature a reinforced, polymer window that enables a wide field of view for infrared inspections.  The clear polymer used in the manufacture of these windows enables the electrician or thermographer to perform a visual inspection, in addition to taking images with any infrared camera.
Each window also includes a hinged, locking cover – for safety and longevity.  These windows can be mounted anywhere on an electrical enclosure, however many of our customers will replace an existing plexiglass panel with the safety of a CAP-CT window.
These windows come in a variety of sizes to meet your specific needs:
  • CAP-CT-6 – 6″ wide IR window
  • CAP-CT-12 – 12″ wide IR window
  • CAP-CT-24 – 24″ wide IR window
  • Custom sized windows always available, upon request

Installation of the IRISS CAP-CT windows is easy.  Each window comes with a stick-on template, that precisely identifies the area to cut out, and where to drill bolt holes.  Simply cut out the template, sandwich the window over the opening and tighten the supplied bolts to secure.
