Is there any sensible way to tighten SWA gland earthing ring nuts?
Even on the smallest size (20mm hole) the gland nut is 24mm or 25mm
and I've never managed to find a spanner of that size that has any
chance of getting at the nut.

You can't tighten from the outside because that would twist the wire -
or is the correct technique to tighten the gland in the box before
tightening the cone nut (if so the DIYFAQ needs to be changed or added
to to indicate this is how to do it)?

I guess a short stub of a box spanner with a tommy bar welded on might
do the job but I doubt if you can get a socket onto the nut, it's too
thin. I don't have any box spanners this big anyway.
