I just had a plumber in who was using a plastic version of the time
honored galvanized strapping. I use the word plastic genericly in this
case, I am not sure exactly what family of materials it belongs in, but
it does meet the plumbing code, and he used the stuff in locations that
were not going to be accessible after sheetrocking.

I just discovered that the poly holding tank in our boat is secured

Gawd, the former owner loved the stuff, it's even holding up the
exhaust hose line.

Obviously, I've got to come up with something else. I can think of a
number of alternatives but, if anyone has done something they think
worked particularly well, I'd like to hear about it. I want to be
able to get the tank out easily and not risk abrading it if it shifts
around with the motion.
