L3-1/2x3-1/2x7/16 (L3.5x3.5x.4375) – L Shapes - Equal Leg Angles
L3-1/2x3-1/2x7/16 is an equal-leg angle with 3.5 in (89 mm) legs, 7/16 in (11 mm) thick, weighing 9.8 lb/ft (14.6 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.
