We have a very old appliance that has an electrical cord with no
strain relief. The cord comes out of a square hole in the back. I have
replaced the original cord with one that it more heavy-duty, but it
still eventually shorts out. I'm going to go get a piece of stiff
tubing about 1" long that will fit into the hole and run the cord
through that. Is there a better idea?


So rather than tell people this idea won't fit or that idea
won't work because you don't know how to work with
that kind of material -- why not post some pictures of
the appliance in question...

At least one showing the cord where it exits the outside
of the case and if you wanted SUPER advice, probably
one of the inside of that point of the machine as well
so that people can actually give you specific gizmos
you could use to solve your problem...
