Six nice massive J-D insulators still in service in northeastern ND. Given their location on the line, they just about have to be changed out 'hot', so they're not going anywhere! The two left-hand pieces and the front ridge pin are U-913s and the other three are U-912s (one has an obvious chip). One of 3-4 such poles on this segment!
