34.9mm Clear Viewport Window Plug | 3.2mm Panel | Polycarbonate
Used to create a transparent panel window without leaving an open aperture, this transparent panel insert is made from clear Polycarbonate to suit a 34.9mm 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.
A transparent head supports simple panel identification tasks, particularly where internal tags, LEDs or colour markers must remain visible. The 38.1mm head diameter and 11.5mm 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
- Larger machinery panels with protected observation points
- Enclosures where internal labels must remain visible
- Control boxes with service indicators behind the cover
- Workshop equipment panels needing a neat clear insert
