Hi steve-I have looked at these pictures a lot but I DO NOT understand what is the purpose of the "little pointy thingies" on the track rails. Please explain.

Haha you are totally right Steve. My parents had a xmas party and we started talking about logging equipment old and new. My Dads buddy, who has worked in the bush running equipment for over forty years called them a zipper link. My friend thats my age and has been a heavyduty mechanic for fifteen years or more said that Cat called them something(I forget what but it was something special being Cat) and he had never heard of them being called a zipper link. Two different generations from the same place can't even agree. Too funny! Looks like a master link to me, just different.lol
