2L3×3×3/16×3/8 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.
2L3×3×3/16×3/8 has equal 3 in. legs, 3/16 in. thick, spaced 3/8 in. back to back.
At 7.42 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 = 0.866 in³ and its moment of inertia Ix = 1.9 in⁴, with a plastic modulus Zx = 1.55 in³.
