B-Line Eaton series strut channel, 1.62" channel height, 240" channel length, 1.62" channel width, Aluminum, 12 Gauge, B22 channel type

The 240 inch B22 stick is bare channel only. You still order the hanging hardware separately: channel nuts (spring or plain) sized for 1-5/8 strut, threaded rod and rod couplings or beam clamps to pick the strut up off the structure, end caps for cut ends, and the conduit clamps or pipe straps themselves. For aluminum runs in corrosive areas, match the fastener metallurgy so you are not setting up galvanic corrosion at every bolt.

This B22 strut is aluminum rather than plated steel, which is the usual pick for wet, coastal, chemical, food-processing and rooftop work where galvanized steel would eventually bloom rust at cut ends and drilled holes. Aluminum also cuts and drills faster in the field. The trade-off is load: an aluminum section carries less than the same steel section, so if you are hanging heavy mechanical equipment, size the run accordingly or go steel.

12 gauge. That is the standard structural strut thickness B-Line uses across the series, and it is what lets the channel lips grip a spring nut without deforming when you torque the bolt down.
