What two factors must be checked when selecting a pulling grip?

When selecting a pulling grip, it is essential to consider the wire size and type. This is because pulling grips are designed specifically for certain types of wire, such as insulated or bare conductors, and they must be compatible with the diameter of the wire being pulled. Using a grip that matches the wire size ensures a secure hold, which is crucial for safety and effectiveness during the pulling process. Additionally, different wire types can influence the grip's design, affecting how it interacts with the conductor and ensuring that the grip does not damage the wire during use. Therefore, assessing both the size and type of wire is critical to achieving a safe and efficient pull.
