I have these 4 pieces as shown. They were used and disassembled. They tighten and fit on a 1 7/8 inch post. Please check the measurements in the picture to make sure they will work for your project.  They are missing 4 out of the 8 total screws that tighten them in place. Please message me if you have any questions and check my other listings for more of these. I will ship them fast and well protected within one business day of payment. Thanks for looking.
