I saw one of these years ago perhaps as a diagram. I well casing is 2" steel and I need to raise the sucker rod about 8 to 12 inches to see if the threads on the joint are history. The pics online these days are so small an 8 year old couldn't decipher them. Can anyone point me in the right direction please? I don't know the top dimension of the coupling but it's a bit over an inch probably. The hole takes a 5/8s bolt.
