TELCOLINE I-37.PAT Morsetto tendicavo per cavi tondi da 3–7 mm, nero

Where standard cable clamps rely on fixed jaw sizes and fiddly screws, the TELCOLINE I-37.PAT uses a self-adjusting wedge mechanism that grips round cables from 3 mm to 7 mm in diameter without any tools. This single clamp covers a wide range of fibre optic drop cables, ADSS cables, and telecom lines, reducing the need to stock multiple clamp sizes. The body is moulded from UV-resistant thermoplastic, while the integrated bail is made of galvanized steel, giving the clamp a tensile strength above 1 kN and reliable performance in outdoor environments.

Highlights

• Tool-less installation: simply insert the cable and tension it – the wedge locks automatically.
• Broad cable compatibility: accepts round cables with diameters from 3 mm to 7 mm.
• Durable construction: UV-resistant thermoplastic body and galvanized steel bail withstand harsh weather.
• High tensile strength: rated for more than 1 kN, suitable for secure aerial or wall-mounted runs.
• Corrosion-resistant materials: ideal for long-term outdoor use in temperatures from -40°C to +70°C.
• Compact and lightweight: easy to handle during installation and reduces load on support structures.

In daily use

Installers will appreciate how quickly the I-37.PAT can be deployed. The clamp is designed for single-use, permanent installations where a reliable hold is more important than reusability. The integrated bail allows mounting on hooks, brackets, or messenger wires, making it versatile for both pole and building entry applications. Its black colour blends discreetly into most environments, and the smooth, snag-free profile helps prevent cable damage during tensioning.
