My brother found the bigger of the two in this picture, in my mom's grass. The smaller clear plastic one (takes two to make a diamond pattern insulator for 3 phase lines running down the street I found on the road about 40 years ago. The yardstick is to give an idea of how big these things are. The power company had been in the area installing the big insulators on their 3 phase lines that the old insulators had failed to hold onto. Probably a part of the Sandy storm cleanup.
