Falling Arc Cover – Efficient Transition in Cable Tray Systems

This 90° falling arc cover is a key component of metal cable tray systems, designed to enable a smooth transition from a horizontal to a vertical (descending) cable route. Manufactured from steel, it ensures durability and reliability under demanding conditions. It is an ideal solution for both professional installers and end-users who value robust and functional installations.

Design and Application

The cover is intended for use with cable trays of 62 mm width and 50 mm height. Its design allows for safe and easy routing of cables vertically, minimizing the risk of damage. Installation is performed using clips, simplifying the installation process and eliminating the need for additional tools. All covers are supplied straight and ready for forming during installation—each is made from a single piece of sheet metal with cut-out sides.

Safety and Compliance with Standards

The falling arc cover is certified in accordance with EN 61537:02, confirming its high quality and safe operation. Additionally, it meets the E30 and E90 fire resistance requirements for maintaining functionality during a fire—an essential feature for public buildings and industrial facilities. The steel construction ensures mechanical and corrosion resistance, while hot-dip galvanizing (version F) further enhances product durability.

Key Product Features:

• Durable Construction: Made from steel, ensuring long-term use even under harsh conditions.
• Easy Installation: Clip-mounting system simplifies and accelerates installation.
• Fire Safety: Compliance with E30 and E90 standards ensures protection of installations during fire events.
• Universality: Designed specifically for cable trays with dimensions of 62 mm width and 50 mm height.
• Precision Engineering: Ensures perfect fit with other components of the KOPOS KOLIN cable tray system.
• Cable Protection: Design minimizes risk of cable damage during vertical routing.
• Ready for Forming: Supplied straight, allowing on-site shaping during installation.

For proper connection, it is recommended to use NSM 6x10 screws—the screw head is positioned inside the cable tray to ensure cable safety. For F-surface (hot-dip galvanized) trays, it is recommended to use GMT-coated screws.
