Sub Duct Ropes

A range of sub duct ropes have been designed to meet the specifications required within the industry. Manufactured in long lengths the polyester core is covered in a variety of polyethylene colours.

The products are made from a polyethylene cover for abrasion resistance and a polyester centre core providing strength. The design promotes a torsionally stable product best suited for installation of optical fibres into sub ducts.
