Mike W Can I use this product to sling a 19-cf pony tank with a 4" diameter?
HENRY M Yes and maybe. I have a 19 , but I have a Seasoft tube that
attaces to the Tank straps.
I use mine for my 50 that I sling.All you have to do is shorten the strap or fold it over and you can use it fo r a 40 or a 72.
Either way it is adjusable. Go for it,
Safe diving,

JAIME M No. It will be to big. I am using it on a 30 ft. pony, and I had to make a small loop because it was to large (besides being made for a 5.25 diameter tank). from top to bottom.
