Understanding the Underground Installation Challenge

When installing cables through underground duct systems, several critical situations require specialized protection:

Crossing Utility Conflicts

Existing water, gas, or telecommunications lines crossing the cable path
Multiple utility corridors with limited separation space
Maintenance of required clearance between different infrastructure systems

Duct Transition Points

Connections between different duct sizes or materials
Entry and exit points from manholes and vaults
Direction changes in the duct pathway

Existing Obstruction Crossings

Passing beneath roads, railways, or other infrastructure
Navigating around foundational elements or structural supports
Crossing through congested utility corridors

The SHS Opening Protection Cable Roller is specifically designed to protect cables at these critical intersection points, where traditional rollers cannot provide adequate protection.
