Cover for 90° downward slope – robust and safe cable passage

This cover, designed for 90° downward slopes in cable tray systems, is a critical component ensuring safe and aesthetically pleasing routing of electrical installations. Manufactured from steel with an electrogalvanized coating, it guarantees corrosion resistance and long-term durability. It is specifically designed for cable trays with dimensions of 50x125 mm, enabling smooth vertical cable transitions.

The cover not only protects cables from mechanical damage but also complies with stringent fire safety standards — it features E30 and E90 fire resistance ratings. This is especially crucial in industrial installations and public buildings, where fire protection requirements are most rigorous. Installation is performed using clips (4 cover holders VU required), ensuring fast and secure mounting.

Design and Installation – Simplicity and Functionality

The cover is supplied in a flat state, and its design allows for easy adaptation to the cable tray during installation. Made from a single piece of sheet metal with cut-out sides, it ensures rigidity and stability. Connection to the tray is achieved directly by insertion and securing with screws (NSM 6x10), eliminating the need for additional connectors. This installation method saves time and reduces installation costs.

Application and Compliance with Standards

This cover is suitable for a wide range of electrical installations — from residential construction to industrial facilities. It is ideal wherever safe and visually appealing vertical cable routing is required. It complies with standards ČSN EN 61537 and fire resistance standards ČSN 73 0895, DIN 4102-12, and STN 92 0205, confirming its high quality and reliability. The sendzimir finish provides additional corrosion protection and ensures temperature resistance from -50°C to +150°C.
