Stainless steel 90° corner bracket Rittal CP 6664.300 for CP 40 enclosures

Rittal CP 6664.300 stainless steel 90° corner bracket is made for use with CP 40 enclosure systems. Manufactured from steel with a stainless finish, this corner bracket provides a corrosion-resistant connection point for cabinet corners, helping to maintain alignment and structural integrity during assembly and routine maintenance. The component is intended as a fixed mechanical accessory to join panels at a right angle and is suitable for environments where a robust, long-lasting stainless connection is required.

Advantages

The stainless steel construction offers enhanced corrosion resistance compared with standard plated steel, extending service life in humid or industrial environments. The 90° geometry and precise manufacturing tolerances ensure consistent panel alignment and a stable joint for enclosures. Its compatibility with CP 40 systems allows straightforward integration with existing Rittal components and mounting points, simplifying installation and replacement tasks.

Suitable for

• Joining CP 40 enclosure panels at a right angle during cabinet assembly
• Industrial and electrical enclosures in humid or corrosive atmospheres
• Retrofit or repair work where original-style CP 40 corner connections are required
• Installations requiring a durable stainless steel corner component for repeated maintenance

When it may not be suitable

This corner bracket is designed specifically for CP 40 enclosure systems; it may not fit or function correctly with enclosure ranges outside the CP 40 family. It is a mechanical connector and does not include seals, gaskets, or insulation—additional components may be required to meet ingress protection or electrical isolation needs.

Key specifications

• Material: Steel with stainless finish (stainless steel characteristics for corrosion resistance)
• Geometry: 90° corner bracket for right-angle panel connection
• Compatibility: Designed for CP 40 enclosure system panels and mounting points
• Function: Mechanical corner connection to maintain alignment and structural stability

How to use

Position the bracket at the corner where two CP 40 panels meet and align the bracket’s fixing holes with the enclosure’s pre-drilled mounting points. Secure the bracket using the appropriate fasteners recommended for CP 40 systems, ensuring even torque to avoid distortion. Check alignment of the panels after fastening and perform any required adjustments. For service or replacement, remove the associated fasteners and lift the bracket away from the joint before installing a new component.

What to consider before purchase

• Confirm compatibility with CP 40 enclosure panels and the required mounting pattern
• Determine whether additional sealing, gasketing, or insulation components are required for ingress protection or electrical isolation
• Verify material suitability for the installation environment (corrosive agents, temperature ranges)
• Ensure correct fastener type and length for secure installation

Usage recommendations

Use stainless-rated fasteners and follow Rittal CP 40 assembly guidelines to preserve corrosion resistance and ensure a stable enclosure assembly. Inspect corner brackets periodically for signs of mechanical stress or environmental degradation and replace if alignment or structural integrity is compromised.
