"hello, my name is sudent 1, would you guys be kind enough to help me out on my assignment ?"

First post..... is it that hard ????
and who told you this forum was packed with plumbers ???

^^^ what have old Falcons got to do with plumbing?

Stop cheating

I went looking for a pic of the old 150mm PVC pipe on roofrack sorta thing plumbers use, to stick here as a p!sstake as its basic and been used for decades.


First result - all the Rhino rack stuff. They want $75 for a damn screw on end cap
You could build the whole damn contraption including brackets and tube, for less than that.
Seriously, $75 for a screw on end cap, for standard 100mm PVC stormwater pipe.

Surely no tradie would buy it.

So, student1..... for your project design a system to undercut that by 90% and you're in.
