The OBO Bettermann cable holder type 2031 20 SP is a mounting component made of polypropylene (PP) in light grey colour (RAL 7035), specifically designed for the orderly and secure mounting of up to 20 electrical cables of type NYM 3 x 1.5 mm² on walls or ceilings. The product features an integrated mounting element, which enables stable anchoring and increases mounting efficiency. The holder is intended for indoor use and is particularly suitable for electrical installations where multiple cables need to be run in parallel.

Applications

The cable holder is used in the field of electrical installation to fix multiple cables simultaneously. It is especially suitable for mounting NYM cables with a cross-section of 3 x 1.5 mm², which are commonly used in residential and commercial buildings. The holder can be mounted on vertical or horizontal surfaces, with installation on walls or ceilings. The recommended mounting spacing when fully loaded is between 250 and 400 mm, with the exact spacing depending on the applicable national standards and regulations.

Functions and equipment in detail

The holder features an integrated mounting element, which is directly moulded into the holder. This element enables secure and quick installation. Mounting is done using hammer or plug anchors, with the mounting hole having a diameter of 6 mm. The holder is also compatible with gas- and battery-powered setting tools from the brands Bosch, Fischer and Spit, with an internal nose diameter of 7 mm. This facilitates installation, especially in larger projects, as the use of special tools increases work speed.

Technology explained simply

The material polypropylene (PP) offers good mechanical stability and resistance to environmental influences such as moisture and temperature fluctuations. The light grey colour (RAL 7035) ensures discreet integration into the environment, especially indoors. The integrated mounting element ensures that no additional parts are required, simplifying installation and reducing the risk of loss or incorrect installation. Mounting is done by inserting an anchor into the 6 mm hole, securing the holder firmly to the substrate.

Compatibility and accessories

The holder is specifically designed for use with NYM 3 x 1.5 mm² cables. Compatibility with setting tools from the brands Bosch, Fischer and Spit enables efficient installation, especially in larger projects. The exact selection of anchors depends on the type of substrate (e.g. concrete, plaster, drywall) and must comply with technical specifications.

Installation and mounting

Installation is done by inserting an anchor into the 6 mm mounting hole. The holder is then fixed at the desired location on the wall or ceiling. When fully loaded with 20 cables, a mounting spacing of 250 to 400 mm is recommended, with the exact spacing depending on the applicable national standards. Installation using gas- or battery-powered setting tools is possible if the internal nose diameter is 7 mm. The holder is intended for indoor use, with no special environmental conditions such as high humidity or aggressive chemicals specified.

Advantages in operation

The cable holder offers a compact and efficient solution for mounting multiple cables. The integrated mounting element reduces the number of required individual parts and speeds up installation. Compatibility with common setting tools from the brands Bosch, Fischer and Spit increases flexibility during installation. The holder is robust and provides secure cable fixation, minimizing the risk of displacement or damage. The light grey colour ensures discreet integration into the environment, especially indoors.
