The National Trail Insulator Club patch is silk screened with a black, sewn border on an aqua background in the shape and image of a CD 145 beehive insulator.  Silk screened on the aqua material is a picture of the top of a pole with two side pins holding green insulators attached to wires.  At the bottom of the patch, in white, are the words "NATIONAL TRAIL/ INSULATOR CLUB."  The patch is 4-3/8 inches wide by 5-3/8 inches tall making it the largest of all the club or show patches.
