All 4 pliers are the latest new design, they open much wider than they used to. The 125 opens about a wide as the old 180, the 180 opens wider than the old 250, 250 wider than the old 300, and the 300 can now tackle 2" pipe!
The Knipex Cobra is the best plier of this kind, beats all other channel lock type pump pliers in every possible comparison. If you've never owned one, now is a great time to gather a 4 pc set, if you've got the old ones, this is a good time to upgrade.
NEW 87 01 125 with this set!
