This idea, recommended by the Chinese safety expert "Ah Sup", gives one something to hold onto, other than the lightly attached fixtures supplied as standard. The grab handle available at any boating store, is fastened through the wall, held in place by a couple of large dia. washers and nyloc nuts.
I think (cant really remember) I used a smear of Sikaflex under the flanges each end, lightly tightened it up, then the next day (after drying) fully tightened the nuts. I had better look (removing an access panel) and check for leaks, in that and the valves.
I'm putting these up, because we are all in isolation, a great time to do these kind of jobs.
