Here is the top view of a RACO Bracket to hold their small porcelain insulators. The way this specific one was used is it was mounted on the top of the crossarm, one wire ended, came down to a cut-out (I also have the exact Cutout that went along with this). On the other side of the cutout, the wire would go back up to the other insulator, and continue on it's way. I have not seen any like this, except for the other one that remains at the pole site. I have only seen the single insulator with the bold at the end. Does anyone know if this is scarce? I would appreciate any info, including if YOU have seen one, or have one, or are interested in this one for sale or trade. Thanks!
