27.8mm-28.6mm Clear Viewport Window Plug | 3.2mm Panel | Polycarbonate
Developed for clean viewing ports in production equipment and service panels, this machine inspection plug is made from clear Polycarbonate to suit a 27.8mm-28.6mm 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 plug helps protect open holes from debris and handling damage, while leaving a visible check point for operators and technicians. The 30.9mm 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
- Inspection openings for larger fuse or label areas
- Electrical cabinet builds with grouped indicator checks
- Industrial panel doors requiring clear sealed viewing points
- Equipment covers used in high-use maintenance areas
