Geometry aid onlyUse the take-up and bend data for the actual bender, and verify final dimensions with a test bend.
Method and field check
Each mark equals the corresponding stub height minus that end's bender take-up. The distance between marks is conduit length minus both mark distances. Check that both stub dimensions are measured from the same finished reference before laying out the bends.
