What is a major disadvantage of using a compression style pulling head?

The major disadvantage of using a compression style pulling head is that it is sacrificial. This means that the pulling head is designed to be used for a limited number of pulls and is often not reusable after a certain point. Compression style pulling heads may become damaged or worn out as they are subjected to significant stress and tension during cable pulls, which can render them ineffective for future use. Consequently, this characteristic can lead to additional costs and the need for frequent replacements.

While other options may have their own disadvantages, they do not encapsulate the core issue associated with compression style pulling heads in the same way that the sacrificial nature does. For instance, while weight can be a consideration in handling and transporting equipment, it does not fundamentally limit the functionality of the pulling head as the sacrificial aspect does. Similarly, difficulty in attachment or expense may vary based on different models and manufacturers, but the fact that the compression style pulling head is inherently designed to be used a limited number of times remains the key disadvantage.
