2L8×6×1/2SLBB 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.

2L8×6×1/2SLBB has a 8 in. long leg and a 6 in. short leg, 1/2 in. thick, in contact back to back.

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

At 46 lb per foot it is one of the 42 2L8×6 sizes, which run from 40.4 to 88.4 lb/ft.

For strong-axis bending its section modulus is Sx = 9.58 in³ and its moment of inertia Ix = 43.5 in⁴, with a plastic modulus Zx = 17 in³.
