2L6×6×3/4×3/4 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.

2L6×6×3/4×3/4 has equal 6 in. legs, 3/4 in. thick, spaced 3/4 in. back to back.

At 57.4 lb per foot it is one of the 27 2L6×6 sizes, which run from 24.8 to 74.8 lb/ft.

For strong-axis bending its section modulus is Sx = 13.3 in³ and its moment of inertia Ix = 56.2 in⁴, with a plastic modulus Zx = 23.8 in³.
