Using double-base safety clips with corrugated jaws on wire rope is designed to ensure a secure grip while minimizing damage to the wire. When properly installed, these clips can efficiently maintain a significant amount of the wire rope's inherent strength.

The correct percentage, 95%, reflects the effectiveness of these clips in transferring the load through the wire rope without causing significant weakening or degradation to its overall integrity. This high percentage indicates that when double-base safety clips are used, they allow the wire rope to retain most of its strength, making them a preferred choice for applications where maximum strength retention is critical.

In contrast, other options represent lower percentages, which would imply more substantial loss of strength in the wire rope when using safety clips. These alternatives, therefore, do not align with the mechanical advantage provided by the double-base safety clips, which are engineered specifically for durability and optimal performance.
