Some heating systems, and an AC system that we have installed. The first two show heating systems where one boiler is wall mounted, and the other is supported by unistrut instead. Sometimes I find it's easier to anchor pipes, pumps, etc. on a few lengths of unistrut then it is to make a bunch of hangers and screw them into the wall.
