Schaefer has a stanchion ring that allows you to add a
lifeline without drilling. They run about $33 each ouch!
I believe they only fit 1" stanchions.
For less money you can buy replacement 2 hole stanchions from Garhauer!

I like open body turnbuckles and the best pelican hooks you
can afford. I'm a big fan of 1x19 (not 7x19) bare wire lifelines,
I will never go back to coated wire. With bare wire we were
able to go up one size for our upper lifelines using the existing holes.
We do have oversize Davis plastic "cable covers" over the
gate sections only to prevent kinking.
That "Drill Steady" looks like it began life as a ground clamp
used to attach ground wires to copper plumbing. They are
about $4 at your local home center or hardware store. They
won't have the fancy thumb screws but if you are only doing a
few...
