Our Viewport Window Plugs provide a practical and visually accessible solution for applications requiring internal component monitoring. Made from high-quality transparent Polycarbonate, these plugs are available in both round and oval styles and include a UL94V-2 flammability rating. Designed to fit securely into a range of panel thicknesses, these plugs allow for safe and easy visual inspection of fuses, indicator lights, sensors, or other internal features without needing to open the housing or panel.
What are Viewport Window Plugs?
Viewport Window Plugs, also known as Window Plugs or Inspection Plugs, are plastic inserts used to seal holes in panels while still allowing for internal visibility. Manufactured from flame-resistant Polycarbonate, these plugs are engineered with built-in locking fingers that accommodate a variety of wall thicknesses. The finish allows for non-obstructive viewing of internal elements such as warning lights or fuse positions, making them ideal for control panels, equipment housings, and enclosures that require routine visual inspection. These plugs provide both a functional and protective role by sealing the opening while maintaining transparency.
