19.3mm Clear Viewport Window Plug | 3.2mm Panel | Polycarbonate

Suitable for OEM assemblies requiring a low-profile clear viewing insert, this viewing window plug is made from clear Polycarbonate to suit a 19.3mm mounting hole and 3.2mm panel thickness. It provides a clear viewing point for enclosed components while giving the panel opening a clean, protected finish.

Its snap-in fit helps create a cleaner installation in sheet metal or plastic housings without requiring adhesive, screws or secondary fasteners. The 21.8mm head diameter and 10.3mm overall height make it suitable for accurately finished panel work where visibility, fit and practical protection all matter.

What Are Viewport Window Plugs?

Viewport window plugs are transparent panel inserts that close an aperture while still allowing internal visibility. They are used where engineers need to view indicators, fuses or internal features without opening the enclosure. Manufactured from clear polycarbonate, these inspection plugs are commonly used in equipment housings, control panels and machinery enclosures where passive visual monitoring is required.

Common Applications

  • Industrial enclosures with fuse or relay viewing points
  • Plant room control panels with quick inspection needs
  • Equipment covers where tamper reduction is useful
  • OEM electrical products needing repeatable fitment
