Subtracting the material thickness from the outside dimension gives you the required offset depth (A). Ok, realized a couple things - (I should've caught this)when bending a saddle you are using a center of bend benchmark (rim notch for 45 on most hand benders) and not the arrow as in an offset, so the multiplier will change based on the difference between the arrow (for offsets) and the rim notch.

Start from a corner or other orienting point, then measure from the corner to where the conduit will end (usually a converter box). To enter a knockout in a box or enclosure V. Multiply the (C-C) measurement of the conduits by the tangent of 1/2 the bend angle. True or False: Parallel offsets can be made with conduit of different sizes by marking and bending at the center or each bend.
