Ridgid is the best IMO, when I worked in the trade we were not allowed to use aluminum Ridgid pipe wrenches, so we always had the cast. From 8" to 4' ( I believe they make up to 5', then it's chain tongs after that) All the plumbers I see on our jobs these days love the Ridgid Aluminum. I have a pair ( straight and offset) 10" Ridgid pipe wrenches that we're my Grandfathers, one of the best things about Ridgid is when the jaws start to wear out you can replace the jaws without replacing the entire wrench. Nothing like slinging 2' pipe wrenches all day long.... Miss those days .....
