Symmetrical reduction cover PRKSP500/400 104650

Robust protection and seamless integration in cable tray systems

The symmetrical reducing cover PRKSP500/400 is a reliable component of the tray system, designed to connect cable trays of different widths — 500 mm and 400 mm. Manufactured from steel with fire-proofed galvanizing, it provides long-term protection against corrosion and external environmental factors. This is a critical solution for installers and users who value durability and safety.

The cover not only protects cables from mechanical damage and dust accumulation but also complies with the E-90 standard, ensuring the continued functionality of building systems for at least 90 minutes in the event of a fire. This is especially important for fire alarm systems, emergency signaling, and evacuation lighting.

Design and Installation

Made from 1.5 mm thick steel sheet, the cover offers high strength and rigidity. Quick installation is another key advantage, enabling efficient execution of installation work. Additionally, the use of locking clips is recommended to ensure even greater connection stability.

Application and Compatibility

The PRKSP500/400 cover is specifically designed for use with BAKS cable trays. It performs reliably in various electrical installations — from commercial buildings to industrial facilities. Thanks to its universal design, it provides an ideal solution for both new installations and upgrades of existing systems. Fire-proofed galvanizing ensures resistance to harsh environmental conditions.

Materials and Finish

The product is available in multiple finish options: steel galvanized by the Sendzimir method (PN-EN 10346:2015-09), steel with fire-proofed galvanizing (PN-EN ISO 1461:2023-02), painted version in standard RAL color palette, or stainless steel — available on request. This allows precise matching of the cover to specific project requirements and aesthetic surroundings.
