Conductor pulling grips and Running Boards are specifically designed to provide a secure, non-damaging connection between the pulling rope and the conductor(s) through various mechanisms:

• Woven Mesh Design (pulling grips): For single conductor pulling grips, the "Chinese finger" or stocking design is key. The woven steel or aramid fiber mesh tightens circumferentially around the conductor as tension is applied, creating a distributed grip over a significant length. This even pressure prevents crushing or localized stress points.

• Optimized Jaw/Clamping Mechanisms (Running Boards): Running Boards for bundled conductors feature individual, articulated clamping mechanisms for each conductor in the bundle. These clamps are precisely designed to grip the outer strands of each conductor securely without deforming the conductor's cross-section or internal components.

• Material Compatibility: The inner surfaces of the gripping elements (whether mesh or clamps) are often designed or coated with materials compatible with the conductor's outer layer (e.g., aluminum, steel, composite), enhancing friction while preventing abrasion.

• Load Distribution: Both types of accessories are designed to distribute the pulling force evenly over a large contact area of the conductor, preventing concentration of stress that could lead to kinking, denting, or strand damage.

• Built-in Safety Factors: All grips and running boards are manufactured with significant safety factors above their rated Working Load Limit (WLL), meaning they are designed to withstand forces considerably higher than their intended operational load.

• Anti-Slippage Design: The geometry and material of the gripping elements are engineered to increase friction under load, actively resisting slippage and ensuring a continuous, controlled pull.

• Clear Conductor Diameter Ranges: Each grip and running board is specified for a precise range of conductor diameters, ensuring a snug and effective fit.

By combining ingenious mechanical designs with appropriate materials, these accessories provide robust and non-damaging attachment crucial for successful stringing.
