Yep, that's how it works.ScubaRon:No, if you look carefully both straps do go through the backplate. It's easier to see on the left side.
The rubber(?) piece is attached to the strap on 2 places and keeps the tank from slipping and also protects its finish.
Loosebits, is this correct?
I see what your saying Jonnythan but the tank does not role in that way. I guess you were thinking that the only thing holding the cam straps to the plate was the wing. This is not the case. The straps go though the plate and there is that rubber piece that is threaded across the straps to hold the tank more securely and to keep the tank and plate from touching each other directly.
Thanks ScubaRon, I didn't get what Jonnythan was talking about and he didn't get what I was talking about.
Here's the cam strap, you can see how it goes through the plate.
