The OBO Bettermann clamp type 3050 LGR is a pressure-ISO clamp made of polystyrene, finished in light grey (RAL7035). It is designed for securing cables, conduits, or other installation components to solid substrates such as masonry or concrete. The clamp features an integrated adhesive foot, a long slot for flexible positioning, and is designed for mounting on M6 threads. It is used in electrical and IT installation technology, where secure and durable fastening is required.

Fastening technology and installation
The clamp can be installed in two ways: either by screwing onto an M6 thread or by adhering to masonry and concrete. For adhesive mounting, the Impu-Fix strip conduit quick adhesive type 509 is recommended, specifically developed for fastening polystyrene clamps. The long slot allows for variable orientation of the clamp, enabling precise positioning even at slightly offset mounting points. The combination of adhesive foot and screw mounting provides flexibility during installation, especially in areas where drilling should be avoided.

Material and construction
The clamp is made of polystyrene, a robust and durable plastic suitable for indoor use. The light grey finish (RAL7035) ensures discreet integration into the environment, particularly in technical rooms or visible installations. The design ensures secure holding of cables and conduits with diameters from 6 to 16 mm. The pressure-ISO technology enables even distribution of load and prevents damage to the secured conduits.

Applications
The clamp is suitable for use in electrical installation, IT infrastructure, and building automation. It is commonly used in conjunction with cable ducts, conduit routing, or for securing sockets and switches. Mounting on masonry and concrete is particularly common in new constructions or renovation projects, where durable fastening without additional drilling is desired. The clamp is not intended for outdoor use, as polystyrene is not weather-resistant.

Compatibility and accessories
The clamp is specifically designed for use with the Impu-Fix strip conduit quick adhesive type 509. This adhesive is developed for fastening polystyrene clamps to mineral substrates such as concrete or masonry. The combination of clamp and adhesive ensures a quick and secure connection that meets the requirements of installation technology. The clamp is not compatible with other adhesives or fastening systems unless explicitly approved for use with polystyrene clamps.

Operational advantages
The clamp offers simple and quick installation, especially when using adhesive type 509. The combination of adhesive foot and screw mounting allows flexible adaptation to different substrates and installation scenarios. The choice of polystyrene material ensures a lightweight yet stable construction that integrates well into installations. The light grey colour provides an unobtrusive appearance, which is advantageous in technical rooms or visible installations. The clamp is designed for indoor use and requires no additional tools or materials, except the recommended adhesive for adhesive mounting.
