Stocking hook for a run-of-the-mill, home store, builder-grade baluster. After cleaning up the print, apply grip tape ("Cat Tongue" or equal) to the inside back and one side. You may need to vary the thickness to get a solid grip, but this holds in place by friction instead of using double-sided tape or wires. The closure is only intended to improve appearance...it helps keep it centered, but that's it.
