B-Line Eaton series strut back-to-back welded channel, 1.62" channel height, 120" channel length, 1.62" channel width, Steel, 14 Gauge, B24 channel ty

The B24A-120GLV is pre-galvanized steel, which is a mill galvanized coating applied to the sheet before forming. That suits dry indoor and protected interior work, mechanical rooms, and covered areas. For exposed exterior, wash-down, coastal, or corrosive environments, specify a hot-dip galvanized or stainless strut instead, since cut ends and welds on pre-galv are not coated.

Back-to-back welded means two channel sections are joined along their backs and welded into one member, so you get openings facing both directions and roughly double the section for the same run. Use it for trapeze hangers spanning longer distances, heavier pipe or conduit racks, and free standing frames where a single 1-5/8 channel would deflect. For light single-run conduit straps on a wall, a single channel is the simpler pick.

Order Eaton B-Line part number B24A-120GLV. B24 is the channel type, 120 is the length in inches, and GLV designates the pre-galvanized finish. Quote that number if you are matching existing strut already installed on the job.

No. This is the bare 120 inch channel only. Spring nuts, hardware, end caps, post bases, and any pipe or conduit clamps are separate line items, so build them into the same order or the crew stops at install.

Yes, 14 gauge pre-galvanized steel cuts cleanly with a bandsaw, chop saw with a metal blade, or portaband. Field cut ends expose bare steel, so hit them with a cold galvanizing compound if the run sees any moisture, and file the burr before sliding a channel nut past it.
