I don't know what is behind your question, but when I installed my plastic bath I wasn't too happy with the two metal support frames supplied.
It seemed to me it lacked support on the end section where I would stand if having a shower. Because of this I fitted additional packing in that area.
The bath does have a wood batten down each side to which the support frames are secured. The battens, I think about 40 mm square section and will of course spread the load. Thinking about it now I think it would be better with three frames.
Sorry, but I couldnt ask my husband about this as he was angry enough.
Ive spoke to him now and he said there was no way it could have fallen off as screws were placed behind the lip at the bottom of side panel and to get it out you would have to lift from the base of the panel. The top is in the groove of bath.
