The center mark is placed past the obstruction center by the shrink allowance. Confirm clearance from the conduit centerline and actual obstacle size.
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 center mark includes the calculated shrink allowance, while return marks are spaced symmetrically around it. Confirm obstacle clearance and bender angle conventions against the actual tool before bending.
