2L3×3×1/4×3/8 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.

2L3×3×1/4×3/8 has equal 3 in. legs, 1/4 in. thick, spaced 3/8 in. back to back.

At 9.8 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 = 1.14 in³ and its moment of inertia Ix = 2.46 in⁴, with a plastic modulus Zx = 2.04 in³.
