At Fibox, innovation begins with listening to our users, collaborating across teams, and making difficult easy. This philosophy guided the ARCA series; durable, corrosion-free polycarbonate cabinets trusted across industries since 2012.
Now, in early 2026, we’re taking ARCA further with the ARCA transparent door, designed to bring clarity, safety, and efficiency to modern electrical installations.
The ARCA story began more than a decade ago when our team recognised a growing need for larger, more robust cabinets that could outperform steel and polyester in harsh environments. As Allan Schultz, Director of Product Management at Fibox, recalls:
“I went myself to 119 customers around Europe because I wanted to hear directly what they needed. The conclusion was clear: corrosion resistance, durability, and flexibility were non-negotiable. That’s how ARCA was born.”
ARCA cabinets quickly became one of Fibox’s most successful product lines, trusted for their strength, UV stability, impact resistance, and reliability in even the toughest conditions.
But as technologies advanced, new user needs emerged. More electronic displays, HMIs, LED indicators and smart automation meant that customers wanted to monitor systems without opening cabinets. This was the spark that led to the idea of transparent doors.
Modern maintenance demands instant status checks without compromising safety or protection. In explaining the inspiration behind the innovation, Schultz notes:
“Touchscreens and displays are everywhere today, and they need protection. But users also need to see them. That’s why transparency became essential: you don’t want to compromise safety by opening the door, but you still need visibility.”
Working closely with Schultz on the transparent door is Anssi Savelius, Global R&D Director at Fibox, who highlights the user benefits:
“With the transparent door, a maintenance worker can instantly check displays or warning lights without even touching the cabinets. That means fewer risks, better safety, and faster reactions.”
These advantages come to life across multiple industries, from building automation and renewable energy to water and waste, factory automation, and traffic control systems. The ARCA transparent door allows you to visually confirm system status immediately, reducing downtime, avoiding unnecessary opening, and supporting both efficiency and safety.
Creating the ARCA transparent door wasn't just about making a clear panel. Instead, it was about rethinking the entire design for better performance and efficiency. As Schultz highlights:
“We can install this door at once, unlike the old method where we cut a hole and glued a window in. This means improved order-to-delivery, stronger impact resistance, and a better price for our customers.”
This seamless, single-moulded unit significantly improves the door's impact resistance and watertightness , while streamlining production. Unlike steel or GRP cabinets that require a glued-in window, the ARCA transparent door is a more robust, reliable, and cost-effective solution.
To ensure durability outdoors, the door is made of a smoked polycarbonate material. This subtle tint acts like protective sunglasses: keeping out UV rays, preventing the material from yellowing or becoming cloudy, and keeping visibility clear for years to come.
The user benefits extend far beyond improved visibility:
Safety: Inspect displays, LEDs, and status indicators without the risk of shock.
Durability: Robust polycarbonate, UV protection, and high IK/IP ratings ensure longevity.
Efficiency: Quick visual checks reduce downtime and simplify maintenance.
Flexibility: Fully compatible with the entire ARCA range and accessories.
Professional appearance: Clean, modern design for demanding installations.
All these advantages reflect Fibox’s focus on making life easier and safer for users. As Schultz puts it: “More transparency, greater impact – that’s what the ARCA transparent door is all about”
The ARCA transparent door launches globally in early 2026. Designed for clarity, safety, and efficiency, it helps users see clearly, act safely, and work smarter.
