About Instrument Protection Windows

Fibox, the world leader in polycarbonate enclosures, presents an innovative view of your controls with the ARCA IPW (Instrument Protection Window). The IPW allows for easy viewing of meters or displays and affords direct access to HMI controls on any enclosure. With a working depth of over 3 inches, Fibox’s IPW provides an easy to install, secure HMI access point on any underlining surface while retaining its NEMA 4X classification. The IPW maintains a water and dust-free environment thanks to a formed in place polyurethane gasket and streamline lockable cover.

Rugged, UV-protected, impact-resistant polycarbonate makes the IPW a robust solution for all cabinets and control panels. With two sizes available (12″x10″x3.31″ and 16″x14″x3.31″), the IPW is made to the same exacting standards of all Fibox enclosures and is UL-listed and rated NEMA 4X, and IP66/67.

Watch our installation video to see just how easy Fibox makes protecting your controls and components.
