Double headed bolts are used to ensure a proper torque level when installing the joint kit. If a torque wrench applies a pressure of 80 N/M to the outer bolt head, the head of the outer bolt and the tag attached to it will be sheared off automatically.

It is possible to remove any joint connection assembly to allow electrical isolation or removal of a busway length without disturbing adjacent busway length.

The remaining bolt head can be re-used when tightened to 85 N/M using a torque wrench.
