Where to buy a 2.5" wrench?

a pipe wrench won't work?

 

If $75 seems on the high side for a wrench, the prices they charge will seem completely absurd. Aside from a single Mac 1-1/4" wrench I needed right away, all of my ASE wrenches 1" and up and metric wrenches 20mm and up are from Craftsman, Kobalt, and even Harbor Freight's Pittsburgh line. It makes no sense to spend $150 or more for a single wrench which will only be used on occasion for tasks which really aren't that heavy (e.g., disconnecting air lines from a compressor to service it, uncoupling hydraulic lines, et. al).

 

if your worried about marks.and a fine looking finish for the next 100 years. use a rag. works every time.

doesn't seem to bother anyone else. certainly not the fire dept. and they got BIG valves.

I've seen plumbers use rags though

 

Harbor Freight, Adjustable wrench or Crescent wrench for another option http://www.harborfreight.com/24-inch-adjustable-wrench-39621.html
