The OBO Bettermann ISO-nail clip type 2014 40 LGR is a fastening element made of polypropylene (PP) in light grey colour (RAL 7035), specifically designed for the secure fastening of cables and conduits to substrates such as wood, concrete or metal. The short design enables compact installation, particularly in narrow or confined installation environments. The clip is equipped with an integrated nail, allowing for quick and tool-free fastening. The cable diameters for which the clip is designed range from 4 mm to 14 mm, with the maximum cable thickness of 14 mm representing the upper limit of fastening capability. The total length of the clip is 40 mm, with the nail itself also being 40 mm long. The choice of polypropylene material ensures high chemical resistance and durability against environmental influences, especially in indoor applications.

Applications
The ISO-nail clip is used in electrical and IT installations to securely and permanently fasten cables, conduits or hoses to walls, ceilings or other substrates. It is particularly suitable for applications in residential and commercial buildings, where quick installation without additional tools is required. The light grey colour (RAL 7035) ensures discreet integration into the environment, especially in indoor spaces with neutral design. The short design reduces installation height and enables fastening in areas with limited space.

Functions and Equipment in Detail
The clip features an integrated nail already mounted in the clip. This allows direct fastening without additional tools or pre-drilled substrates. The cable opening is designed for diameters from 4 mm to 14 mm, with the maximum cable thickness of 14 mm representing the upper limit of fastening capability. The clip itself is made of polypropylene, a thermoplastic material known for its high strength, resistance to moisture and chemical influences, as well as its low density. The light grey colour (RAL 7035) is standard and ensures visual harmony with many building components.

Technology Explained Simply
The construction of the ISO-nail clip is based on a simple but efficient principle: the clip encloses the cable and is pressed into the substrate using the integrated nail. The material thickness and shape ensure that the cable is securely held without being damaged. The short design reduces installation height and minimizes visual presence. Polypropylene (PP) offers good resistance to UV radiation, moisture and everyday chemicals, extending the service life of the clip in indoor environments. The RAL 7035 colour is a standard in the construction industry and is frequently used for technical building components.

Compatibility and Accessories
The ISO-nail clip is compatible with cables and conduits in the diameter range of 4 mm to 14 mm. As an accessory, the BFM-NSMN 10-14/40 grey nail clip 10–14 mm with nail in grey, shaft 40 mm is offered, which serves a similar function but may be designed for different substrates or requirements. The use of additional fastening elements is not required, as the clip is already equipped with the nail.

Installation and Mounting
Installation is tool-free: the cable is inserted into the clip opening, and the clip is pressed into the substrate using the integrated nail. Force transmission occurs via the nail, which penetrates the material and secures the clip. The short design enables quick and precise installation, especially in confined spaces. No additional tools or preparations are required. The fastening is durable and resistant to mechanical loads in indoor environments.

Operational Advantages
The ISO-nail clip offers quick, tool-free installation, reducing time and effort. The integrated nail fastening eliminates the need for separate fastening elements. The choice of polypropylene material ensures high service life and resistance to environmental influences. The light grey colour (RAL 7035) ensures discreet integration into the environment. The short design enables flexible application in confined spaces without impairing functionality. The fastening is secure and reliably holds cables within the specified diameter range of 4 mm to 14 mm.
