Which statement about center bends in a four-bend saddle is true?

• A. The center bends on a four-bend saddle are equal to the side bends.
• B. The center bends on a four-bend saddle are not equal to the side bends.
• C. The center bends on a four-bend saddle are unrelated to the side bends.
• D. The center bends on a four-bend saddle are twice the angle of the side bends.

Answer: (A)

Center bends in a four-bend saddle are equal to the side bends because the saddle is designed to be symmetric with a uniform curvature. In this arrangement, each bend turns the conduit by the same angle, so the path stays balanced and the centerline remains aligned as it wraps around the saddle. If a center bend were larger or smaller, the geometry would become asymmetric, causing misalignment or an abrupt change in direction. Treating the center bends as equal to the side bends reflects the expected, balanced shape of a standard four-bend saddle.
