OEM Crescent 10-in Hook Jaw Kit Pipe Wrench - Repair Parts - (Aluminum) #C10HOOK.  This is not the entire wrench, this listing is for replacement of the hook jaw of a pipe wrench and includes the other 2 parts like the spring.  You might not need all three parts but they all come together sealed.  I am only selling the 3 piece kit.  This is much cheaper than buying a new wrench.  I have about 24 of these and they are all brand new.  This includes all the parts other than the main handle.  The metal is aluminum for the jaw and the spring is steel.   If you would like to make a deal for over 4 then I would give you a different price because of shipping being a lot cheaper.  I will ship USPS mail.
