About this 3D model
The support Version 2 is for a ladder line (G5RV ect.) and fits inside of a 1 inch schedule 40 PVC pipe (very snug) for the cross arm support. The part insert is about .82 inches. The wire bracket is beefed up from version 1 which has wire brackets of .06 and the version 2 has wire brackets of .13 for more strenth. There is a hole at the end of the holders to place a wire tie or a bolt to secure the end. If you need one with a thicker insert let me know and I will post it for you. These were printed horizonal in PLA.
