Will this rack hold steel 80s or is it designed for tanks with a smaller circumference like a standard aluminum 80?
I USE IT FOR 3 ALUMINUM 80'S AND IT'S PRETTY SNUG!
I have steel 100's in mine.
Yes the tank racks will hold steel 80s and any other sizes you may have . They are great for the car and boat.
Sorry, I have no clue. I am only the supportive wife of a scuba diver.
It holds the aluminum 80 but I use it to hold 2 aluminum 80's and one steel 130 with no problem. I just ensure my tanks are all secured in the bed of my truck.
I used them with aluminum tanks but I don't remember if they could fit thicker tanks, although they were soft cushion(y) material so maybe they would. Unfortunately I don't have them with me so I can't check for you.
