Q: Are these straight or angled? Serviceable? Repair kits available?
A: 1) These WS-1180RS "(RS)" Wrenches are reversible by flipping the wrench over so they are straight at the ratchet end.
2) There is a WS-1170RCU "(RCU)" set that is reversible by flipping a reverse lever and they are angled.
3) All Williams ratchet wrenches have a life time warranty so any failure due to wear would fall under factory warranty.
