Internal corner for duct direction change Bettermann WDK 60x60 (model 6192017)

Bettermann internal corner WDK 60x60 (model 6192017) is a metal accessory engineered to create a fixed 90° internal turn in rectangular ventilation or cable duct systems with a 60 x 60 mm cross-section. Designed for commercial and industrial electrical and HVAC installations, this component enables precise change of direction while maintaining a compact installation footprint and a clean interior path for cables or airflow.

Advantages

The internal corner is made of corrosion-resistant metal and formed to fit standard 60 x 60 mm rectangular duct profiles, providing structural integrity at a bending point and reducing stress on routed cables or conduits. Its precise dimensions allow straightforward alignment with adjacent duct segments, simplifying assembly and ensuring consistent interior clearance. The robust construction supports repeated handling during installation and contributes to long-term system stability.

Suitable for

• Routing electrical cables in commercial and industrial cable duct systems
• Changing direction of rectangular ventilation ducts in HVAC applications
• Compact routing in plant rooms, data centers, and service shafts
• Retrofit projects where a fixed 90° internal turn is required

Key specifications

• Cross-section compatibility: 60 x 60 mm rectangular ducts
• Function: fixed 90° internal corner for direction change
• Material: metal construction suitable for industrial use
• Installation type: for attachment to standard duct segments to form an internal bend
• Application areas: cable management and ventilation ductwork

How to use

Position the internal corner at the required junction between two duct segments aligned for a 90° internal turn. Ensure mating faces of the duct segments are clean and correctly oriented before joining. Secure the corner to adjacent duct sections using the recommended fasteners or clip system compatible with the duct profile to achieve a stable connection and maintain interior clearance for cables or airflow. Verify alignment and clearance after installation and make any necessary adjustments to adjoining duct runs.

Usage recommendations

Before installation, confirm that the duct profile and supporting structure can accommodate the internal corner and the expected mechanical load. Maintain recommended separation and bend radii for sensitive cables to prevent damage. For HVAC uses, check that the internal corner does not create excessive airflow restriction for the system design. Follow local regulations and industry standards for cable management and duct installation during planning and installation.
