L7×4×3/8 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.
L7×4×3/8 has a 7 in. long leg and a 4 in. short leg, 3/8 in. thick.
At 13.6 lb per foot it is the lightest of the 5 L7×4 sizes, which run from 13.6 to 26.2 lb/ft.
For strong-axis bending its section modulus is Sx = 4.42 in³ and its moment of inertia Ix = 20.5 in⁴, with a plastic modulus Zx = 7.81 in³.
