• Overview
The WellTools CLoad Disconnect is an extremely robust drop ball safety release tool. It allows a stuck Coiled Tubing BHA to be detached at a pre-determined point leaving an Internal Fish Neck for subsequent fishing operations.
The CLoad Disconnect offers excellent resistance to impact, vibration and high bending loads, making it ideal for running below impact tools when required.
