L4x4x5/16 (L4x4x.3125) – L Shapes - Equal Leg Angles

L4x4x5/16 is an equal-leg angle with 4 in (102 mm) legs, 5/16 in (8 mm) thick, weighing 8.2 lb/ft (12.2 kg/m).

Equal leg angles are one of the simplest and most versatile structural sections, with two legs of the same size meeting at a right angle. Their simplicity is their strength: angles are inexpensive, easy to cut, drill, bolt and weld, and useful almost anywhere a structure needs bracing, a connection element or a lightweight framing member. Common applications include diagonal bracing, truss web members, framing clips and connection angles, ladder and frame components, and general-purpose fabrication work where a full I-shaped or channel section would be unnecessary.
