I have a 5' by 5' square shaft that I am passing a 3" pipe through. Can I get a 4 inch offset inside that 5' space? I have found a shop that will bend it for me I just did not ask them. I probally could use prebent 45's as well?
Yes you could get the 4" offset in 5' with a bender . Most likely with 22 degrees , maybe 30 degrees. Since you dont have a bender maybe you could roll the offset with the factory 45 degree bends.
