OBO Bettermann KS90-400 R=300 Cable Tray Corner Piece, Hot-Dip Galvanized

The OBO Bettermann KS90-400 R=300 cable tray corner piece is a professional-grade component engineered for the seamless redirection of cable tray systems. Designed with a 300 mm radius and a 400 mm width, this fitting allows for smooth cable routing around corners while maintaining the structural integrity of the cable management installation. The hot-dip galvanized finish provides superior protection against environmental factors, ensuring long-term reliability in demanding conditions.

Advantages

This corner piece offers exceptional durability due to its hot-dip galvanized steel construction, which effectively prevents corrosion even in harsh or outdoor environments. The 300 mm radius is specifically designed to maintain the required bending radius for sensitive cables, preventing damage and signal loss. Its robust design ensures that the cable tray system remains stable and secure, providing consistent mechanical protection for electrical wiring throughout its service life.

Suitable for

• Industrial electrical installations
• Outdoor cable management systems
• Infrastructure projects requiring high corrosion resistance
• Commercial building cable routing

When it may not be suitable

This component is not suitable for applications requiring non-metallic or lightweight plastic cable management systems. It is also not intended for use in environments where specific chemical resistance beyond standard hot-dip galvanization is required, or for installations where a different tray width or bending radius is specified by the project design.

Key specifications

• Width: 400 mm
• Bending radius: 300 mm
• Material: Steel
• Surface finish: Hot-dip galvanized
• Component type: 90-degree corner piece

How to use

To install the corner piece, align it with the ends of the existing cable tray sections. Secure the fitting using appropriate connectors and fasteners compatible with the OBO Bettermann system. Ensure that the tray is properly supported at the corner to prevent sagging or mechanical stress on the joints. Verify that all connections are tightened according to standard installation practices to maintain electrical continuity and structural stability.

What to consider before purchase

• Verify that the 400 mm width matches your existing cable tray system.
• Ensure the 300 mm radius meets the minimum bending requirements of the cables being installed.
• Confirm that the hot-dip galvanized finish is appropriate for the intended environmental exposure.
• Check for compatibility with your specific cable tray mounting hardware.

Usage recommendations

For optimal performance and safety, always ensure that the cable tray system is properly grounded and that all fasteners are tightened to the manufacturer's recommended torque specifications. Regular inspections are advised to ensure the integrity of the installation in outdoor or industrial settings.
