I need piece on support pole where 3/4 pole slides into 7/8 pole and set screw tightens tension
Hi,
Check on this page

then scroll down until you find eye ends. Then look for adjustable eye ends. These eye ends fit on the outside of the pipe and a screw in each eye end adjusts the tension just by turning the pole in your hand. Ingenious little contraptions, but expensive. That will be about the best I can do for you. Let me know if you have any more questions abut this, it should work well for you.
