I cannot bust this cleanout cap free to save my life and I'm afraid
that I'm going to strip it with my adjustable wrench or pipe wrench.
Some are square but some are not - this one is not. I'm thinking it's
1 5/16" My biggest socket is 1 1/4 and its a no go.

I've done this on a spa repair. Cut off the top of the square cap. Cut two
radial cuts from the center out with a hack saw blade or a saber saw. Pick
a place where the plastic that is sticking up will give you something to
grasp with the pliers. Where they come in contact with the outside of the
circle should be about 1/2". DO NOT CUT INTO THE THREADS. Carefully, with
pliers and whatever you can use, remove the small wedge. The rest of the
plug will be easy to rotate by grasping it with pliers on one of the three
remaining vertical walls of the square cap. Take your time. Take care not
to damage the threads.

A couple of problems - it's not a square cap that's why I was asking
what socket size. Secondly, it's not plastic it's brass. Brass cap
on a cast iron line.
