The way I supported mine was to take a wooden dowel rod, about 5/8" dia., and
wound a stainless steel wire around it making a spring about like what you
might find holding together your notebook. I placed the whole deal in the
hose, and pulled out the dowel, which sort of let the wire expand to the i.d.
of the hose. I'm confident in it's performance.
