A three-point saddle bend clears an obstacle in the conduit path using three bends: one center bend at a larger angle and two outer bends at exactly half the center angle. The most common saddle uses a 45° center bend with 22.5° outer bends. The key measurements are the height of the obstacle, the distance from the first mark to the center of the obstacle, and the multiplier for the distance between the center and outer bends (for a 45° saddle, the distance from center to each outer mark is height × 2.5). The center bend is made first, then the conduit is flipped to make the two outer bends. This calculator provides all three mark locations from your reference point.
2.5" obstacle, 45° center/22.5° outer saddle: Distance from center to each outer mark = 2.5 × 2.5 = 6.25". Mark 1 at 18 − 6.25 = 11.75"; Center mark at 18"; Mark 3 at 18 + 6.25 = 24.25". Make the 45° center bend first, flip for the two 22.5° outer bends.
This is a variant of the full Conduit Bending Calculator — which supports all bend types with live 3D visualization and supports EMT, rigid, and PVC conduit sizes.
