How to tighten a 50mm SWA gland with no access to locknut

No slots,
I've done that myself before on a temporary job running single cables from a generator to a steel enclosure acting as a JB
I could be wrong but I have never heard of any gland which stops this being a problem

It will be a problem if the panel is of magnetic material regardless of what material the bushes or glands are made of. I'm really not buying this magic gland story, if it was the engineers that came up with that pile of baloney it's either some private joke they've got going on or I think they might actually be taking the ----.

I’m not aware of any magic glands that will stop eddy currents in magnetic material.
Whenever I’ve installed cables in transformers, the gland plate has always been non-magnetic.
Sometimes a right pain to drill.

Yep, it would be magic if a gland prevented eddy current heating .

I had a similar problem once. Solution was to MIG-weld pairs of nuts either side of a spacer so that each stopped the other from turning. Sprayed over the weld with cold galv afterwards. You could weld or braze them all to a spine if you could get it in as a single piece. More risk of them not lining up with the holes in the DB though.

Hmm, perhaps a solution would be before installation, to weld a short bar of steel between the lock nut and the 6mm Banjo bolt nut?
Another option would be to cut out and thread a small rectangle of plate steel so that both the Banjo bolt and the gland can be screwed through holes in the panel into the steel plate?

Yes they're just bog standard metallic stuffing glands
Basicly the guy doesn't want to redo the job, I made sure the French customers electrical Engineer knew I thought it was a load of rubbish and advised him to ask for proof of this , I thought he would press this but he's been away now on holiday for 4 weeks

Some good ideas for the gland problem very much appreciated definitely gives me other options to try so thanks to all who have contributed!

Let us know how it goes and post some pics if you've got time.

Do you mean can only tighten from bottom. If so get a steel lock nut, weld a long side piece of steel to it. So when spins locks against casing. Job done. Used to weld lock Nuts to gland plates to make tightening easier. Then obliviousy paint welds.
