The cable gland is a long, flexible fiber cable with a tensioning eyelet at one end and a flexible, elastic head at the other. It is used to thread electrical cables into corrugated pipes. Perlon® is a patented German-made material with high mechanical properties, long life, and non-deformability. Its flexibility allows for easy insertion into 20-25 mm tubes, optimizingworking times and methods.It features a flexible curve-guiding tip and a threaded rod with an interchangeable eyelet. It offers excellent tensile strength and excellent bending ease; it is non-conductive, ensuring safe use. The 4 mm diameter Perlon probe is suitable for residential electrical installations and is ideal for short, winding sections. The interchangeable brass fittings are threaded directly onto the Perlon; with a high breaking load, they are practical and easy to replace. Advantages: affordability, tensile strength and practicality. German plastic, Made in Italy product.
