To order a multi-branch lateral (or manifold), first give the dimensions of A, B, C, D, E, F, G, etc. Then give the branch angle (45°standard) and the radial angles if needed.
Example 1: 12 x 6 x 3 x 4 x 5 x 6 x 7 with 45° branch angles. All branches at radial angle 0°
Example 2: 8 x 6 x 4 x 4 x 4 x 4 with 45° branch angles. Branches C and E at radial angle 0°. Branches D and F at radial angle 180°.
