2L3×2×1/4×3/8SLBB 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.

2L3×2×1/4×3/8SLBB has a 3 in. long leg and a 2 in. short leg, 1/4 in. thick, in contact back to back.

It is a double angle set with its short legs back-to-back.

At 8.2 lb per foot it is one of the 30 2L3×2 sizes, which run from 6.14 to 15.4 lb/ft.

For strong-axis bending its section modulus is Sx = 0.515 in³ and its moment of inertia Ix = 0.779 in⁴, with a plastic modulus Zx = 0.926 in³.
