What is the primary advantage of using a 3-point saddle bend?

Using a 3-point saddle bend primarily offers increased structural support, which is particularly important in applications where durability and strength are crucial. This design minimizes stress concentrations that can occur in a simple two-bend structure, resulting in a more robust system capable of accommodating load variations and environmental stresses.

The additional point of support helps to distribute forces more evenly, which enhances the overall integrity of the structure. This is vital in many industrial applications where the raceways are subjected to mechanical impacts, thermal expansion, or other forces that could compromise their stability.

In contrast, options focused on aesthetics, material costs, or installation flexibility do not address the primary concern of structural integrity and support that is achieved through this design. Thus, while those other aspects may have their own relevance, they do not surpass the critical advantage of enhanced structural support that comes with a 3-point saddle bend.
