Rolling offset calculator for conduit
Offset and roll in one run — without doing the triangle in your head.
A rolling offset combines an offset with a roll so the pipe lands where the rack or box needs it. BendLogic gives true offset, travel, and roll with a visual layout you can check before marks go on the stick.

01 / Field notes
What “rolling offset” means on the job
You need to move the run in two directions at once (for example up and over). That is more than a simple offset: you need the combined distance and the roll so both bends land. Mistakes show up as twisted racks and wasted pipe.
