Duct Mandrels

Duct Mandrels for Duct Proving & Network Installation

Duct mandrels are essential tools for proving the integrity and internal diameter of cable ducts before fibre optic or utility cable installation. Designed to identify obstructions, deformations and damaged sections, they help ensure ducts are suitable for cable pulling and blowing, reducing installation delays and costly rework. At Telenco UK, we supply a comprehensive range of duct mandrels for professional telecommunications and utility network projects.
