2L8×8×1/2×3/8 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.
2L8×8×1/2×3/8 has equal 8 in. legs, 1/2 in. thick, spaced 3/8 in. back to back.
At 52.8 lb per foot it is one of the 21 2L8×8 sizes, which run from 52.8 to 114 lb/ft.
For strong-axis bending its section modulus is Sx = 16.7 in³ and its moment of inertia Ix = 97.6 in⁴, with a plastic modulus Zx = 30.2 in³.
