No wonder my phone never worked right,
using 12" pipe wrenches on 3/8 terminal block nuts.....*
The large Trimo's are good working tools btw, well worth the $2, I think the not so pretty ones I have in large sizes cost me more like $20...
The slip jaw pipe wrench (30") I have had probably 25 years,has never lost a fight with a pipe fitting. (and, no, I have not been kind to it, pipe wrenche are not meant for kind people ; )
