That's a conduit fitting, not a trunking fitting, but otherwise a neat bit of improvisation.

It Was a short piece of plastic tube I found in the bits and pieces draw which after a little internal boring on the centre lathe fitted the coin cells very well. The dowel came from an old cricket stump and the brass screws were M4 which threaded into the dowel quite nicely giving good tension on the coin cells. I could have spent more time sourcing plastic inserts but it does the job!
Conduit, tube, trunkiing does it really matter?
