L7x4x1/2 (L7x4x.5) – L Shapes - Unequal Leg Angles
L7x4x1/2 is an unequal-leg angle with 7 in (178 mm) x 4 in (102 mm) legs, 1/2 in (13 mm) thick, weighing 17.9 lb/ft (26.6 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.
