2L3×3×7/16 double angle
Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.
2L3×3×7/16 has equal 3 in. legs, 7/16 in. thick, in contact back to back.
At 16.6 lb per foot it is one of the 18 2L3×3 sizes, which run from 7.42 to 18.8 lb/ft.
For strong-axis bending its section modulus is Sx = 1.89 in³ and its moment of inertia Ix = 3.96 in⁴, with a plastic modulus Zx = 3.4 in³.
