B Series Cable Entrance Roller — Durable Heavy-Duty Steel Structure with High-Strength Nylon/Aluminum Rollers for Underground Power Installation

The B Series Cable Entrance Protection Roller is a heavy-duty guiding tool designed to protect power cables when entering underground ducts, manholes, or trench openings. It significantly reduces friction and prevents cable jacket damage during cable pulling or laying operations in power construction projects. Suitable for medium- and high-voltage cable installation, it provides smooth, stable, and safe cable entry under various construction conditions.

The B Series Cable Entrance Protection Roller is a duct-entry guiding device equipped with a durable steel frame and high-strength rollers. It is installed at the entrance of a cable duct to guide the cable into the underground system while maintaining proper bending radius and minimizing abrasion.
