Back to the hemet mount.

I googled the PB3H, and from what I can see (correct me if I am wrong) there are a couple of recesses, one in each end, from which it is suspended and a weight at the bottom.

Soooooo......

I got thinking.

I don't know about width, but if this is wide enough, without being too wide, fit a couple of 90deg angle joiners to it can suspend, and wrap a bit of lead or something round the bottom.

Maybe you can come up with a better idea, but it is a thought
