The dividers are done up with a bolt shaped like a tent peg which runs through 3 circular tubes of steel, (one on the divider itself and one either side of it attached to the side of the float.).
I hate them, if a horse goes down or gets panicked and is pressing against the divider I don't think you could get them out.
I have a vague idea in my head of what I would like but my husband says it can't be done.
SO, what systems do other people's floats have.
