Cutting PVC conduit in tight spaces and trenches is as easy
as using a hacksaw in open space. And you can do it just
by using a cotton string line like the ones bricklayers use.
Just make sure it is a cotton string because nylon will
either burn away or melt into the PVC.
Place the string around the conduit and simply saw
back and forth to wear and burn away the cut. This
method will be greatly appreciated when you have to dig
up a conduit and cut it in the trench!

Templates may be useful for when a gang of conduits have to
be mounted to a wall or other surface.
Set-up the conduits on a bench or floor with saddles in
place, adjusted for the best look and fit. Using a sheet metal
template, your first-year apprentice should be able to drill
appropriate holes to a chalkline, or any suitable datum.
Then, with the holes pre-drilled, conduits can be fitted fast
and easily without having to juggle them up a ladder while
holes are being drilled.
