20.8mm x 22.2mm Clear Oval Viewport Window Plug | 3.2mm Panel | Polycarbonate

Engineered for enclosure apertures where visibility and protection both matter, this clear enclosure plug is made from clear Polycarbonate to suit a 20.8mm x 22.2mm 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.

The material is suited to electrical and mechanical panel work where a flame-rated clear component is preferred for inspection areas. The 54.4mm x 26.6mm head diameter and 11.7mm overall height make it suitable for accurately finished panel work where visibility, fit and practical protection all matter.

What Are Viewport Window Plugs?

Oval viewport window plugs are transparent polycarbonate inserts used where a wider or elongated inspection area is required. They help create a protected viewing window for non-round cut-outs while still giving a neat snap-fit panel finish. 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

  • Oval panel cut-outs for specialist equipment
  • Wide indicator windows on control housings
  • Machine fascia panels needing elongated viewing access
  • Custom electrical enclosure builds with non-round apertures
