A come-along grip relies on which action to effectively grip conductors?

A come-along grip operates effectively by utilizing wedge action, which is crucial for securely gripping conductors. The design of the grip incorporates a series of inclined surfaces that come into contact with the conductor. As the grip is tensioned, the wedges create a mechanical locking effect that holds the conductor firmly in place, preventing slipping during use.

This wedge action is particularly effective for maintaining strong grip on various types of conductors under the tension and load they may experience in practical applications. By increasing the pressure and locking the conductor securely, it ensures both safety and reliability, which is essential when working with electrical lines or rigging systems. The use of wedge action distinguishes it from methods that might only rely on pulling or sliding, which can introduce instability or insufficient grip.
