I was fitting a copper bulkhead fitting for 2" pipe. My spanner collection didn't cover the size.
Probably could have got by with something, but decided to try this project.

24mm socket/spanner of 1/2" drive ratchet can be used to turn the tool.

Tool is only required to nip-up the fitting, it is being used in a low pressure application. The tool might not be suitable for applications requiring high torque.

It is of no use when trying to tighten the nut/olive onto the pipe as a high torque is required.
The "nut for the fitting and the "nut" for tightening onto the olive are different "across flats" size
