The 2031 20 cable holder from OBO Bettermann is a mounting component made of polypropylene (PP) in light grey colour (RAL 7035), specifically designed for the orderly routing and securing of up to 20 electrical cables of type NYM 3 x 1.5 mm² on walls or ceilings. The product features an integrated moulded mounting element, enabling secure and durable installation. The holder is designed for indoor use and is suitable for electrical installations requiring structured and accessible cable routing.

Applications
This cable holder is used in electrical installations, particularly for securing multiple cables in a bundle. It is suitable for mounting on vertical or horizontal surfaces such as concrete, plaster, or drywall, with fastening achieved using hammer or push-in anchors. The holder is also compatible with gas- and battery-powered setting tools from brands Bosch, Fischer, and Spit, where the nose diameter inside is Ø 7 mm. This enables efficient and rapid installation, especially in larger installations.

Functions and Features in Detail
The mounting element is directly integrated into the holder and provides a mounting hole diameter of 6 mm. The holder is dimensioned to accommodate up to 20 cables of type NYM 3 x 1.5 mm², with cables routed in parallel. The light grey colour (RAL 7035) ensures discreet integration into the environment, particularly in technical rooms or visible installations. The choice of polypropylene material ensures high mechanical stability and resistance to environmental influences such as moisture or temperature fluctuations.

Technical Explanation
The integrated mounting allows for quick and secure installation without additional components. The moulded element ensures a firm connection between the holder and the fastening element, minimizing the risk of loosening or displacement. The holder is designed for maximum load capacity, determined by the number of secured cables and their cross-section. Recommended mounting spacing is 250 to 400 mm, with exact spacing depending on applicable national regulations and standards. This ensures stable and secure cable routing over long distances.

Compatibility and Accessories
The holder is specifically designed for use with cables of type NYM 3 x 1.5 mm². Fastening is done using hammer or push-in anchors, with compatibility confirmed for gas- and battery-powered setting tools from brands Bosch, Fischer, and Spit. The tools must have an internal nose diameter of Ø 7 mm to correctly secure the holder.

Installation and Mounting
Installation is performed by inserting a hammer or push-in anchor into the pre-drilled hole in the wall or ceiling. The holder is then slid over the mounting element and connected to the anchor. When using setting tools, the holder is placed directly into the tool and secured by striking or pressing. The recommended mounting spacing of 250 to 400 mm must be maintained to ensure stable fastening. The exact spacing depends on current national standards and regulations.

Operational Advantages
The 2031 20 cable holder provides a reliable and durable mounting solution for multiple electrical cables. The integrated mounting reduces installation time and minimizes the risk of errors. The use of polypropylene ensures high mechanical strength and longevity. The holder is easy to install and enables clear cable routing structure, facilitating maintenance and inspection. Compatibility with common setting tools increases efficiency in larger installations.
