    Abstract: A saddle member for a saddle clamp has a generally U-shaped cross section and is made from a flat sheet metal blank by a series of folding, punching and welding operations. In the finished saddle member, generally parallel side walls are spaced apart and have arcuate free ends. A base extends between the side walls opposite the free ends, and end walls extend between the side margins of the side walls. The end walls include flanges on the side walls and the base and weldments that extend along substantially the entire lengths of the side-wall flanges to provide end walls that form continuous surfaces with both the side walls and the base.
