Geometry aid onlyDisplayed marks are rounded to the nearest 1/16 in. Confirm take-up, multipliers, bend radius, and mark-pointer alignment for your conduit and bender. Make a test bend and verify the finished dimensions.
Method and field check
The mark location equals desired finished stub height minus bender take-up. Take-up varies by bender, conduit size, and material. Use the value marked on the bender or in its instructions and verify the result with a test bend.
