The 2-Jaw grabber is optimized for general retrieval and holding tools, while the 3-Jaw grabber uses a 3-point contact geometry to provide superior stability and self-centering for cylindrical or irregular objects, such as pipes and valves. Choosing the correct head depends on your target object’s shape: the 2-Jaw excels in versatile gripping, while the 3-Jaw is engineered for precision centering on round hardware.
