L4x3-1/2x1/2 (L4x3.5x.5) – L Shapes - Unequal Leg Angles
L4x3-1/2x1/2 is an unequal-leg angle with 4 in (102 mm) x 3.5 in (89 mm) legs, 1/2 in (13 mm) thick, weighing 11.9 lb/ft (17.7 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.
