L4x3-1/2x5/16 (L4x3.5x.3125) – L Shapes - Unequal Leg Angles

L4x3-1/2x5/16 is an unequal-leg angle with 4 in (102 mm) x 3.5 in (89 mm) legs, 5/16 in (8 mm) thick, weighing 7.7 lb/ft (11.5 kg/m).

Unequal leg angles have two legs of different sizes meeting at a right angle, which lets you place the longer leg where the span or connection needs it. They share the practical advantages of all angles: inexpensive, easy to cut, drill, bolt and weld, and useful wherever a structure needs bracing, a connection element or a lightweight framing member. The unequal geometry suits lintels over doors and windows, shelf angles, unequal-leg bracing, truss members and general fabrication work where one direction carries more load than the other.
