B-Line Eaton series strut channel, 1.62" channel height, 120" channel length, 1.62" channel width, Steel, 14 Gauge, B24 channel type, Stainless steel

It is type 304 stainless steel, not a painted or plated carbon channel. Type 304 handles outdoor, damp and washdown environments, which is why it gets specified for rooftop supports, food service areas and mechanical rooms where galvanized strut would eventually rust at cut ends. Cut ends of 304 do not need field touch-up paint the way pre-galvanized channel does.

14 gauge is the full-strength wall thickness used for general structural strut runs, as opposed to the lighter gauges sold for light-duty pipe and conduit support. On this Eaton B-Line B24 section it is paired with the 1.62 by 1.62 inch profile, so you get the standard strut stiffness in a 304 stainless body rather than a coated carbon one.

Where the run sees salt air, chemicals or regular washdown, the 304 stainless B24 is the one to specify. Galvanized and pre-galvanized strut is the cheaper choice for dry indoor mechanical and electrical work, but it corrodes at field-cut ends and drilled holes. If the spec on the drawing calls for stainless supports, match the fasteners and fittings in stainless too, since mixing carbon steel nuts into a stainless run reintroduces the rust point you were trying to design out.

No. This is the bare 120 inch channel section only. Channel nuts, spring nuts, bolts, end caps, conduit clamps, pipe straps, threaded rod and any post bases or brackets are ordered separately. Plan on stainless fittings to keep the assembly consistent with the 304 channel.
