B-Line Eaton series strut channel, 2.43" channel height, 120" channel length, 1.62" channel width, Steel, 12 Gauge, SH hole pattern, B12 channel type,

Pre-galvanized is the right call for indoor and covered dry work: mechanical rooms, ceiling runs, plenum supports, electrical rooms, parking structures under cover. The zinc goes on the coil before roll forming, so the cut ends and the punched slots are bare steel. For direct weather exposure, wash-down areas, pool rooms or coastal work, order hot-dip galvanized or stainless channel instead of this pre-galvanized B12.

SH is B-Line's slotted-hole back pattern, so the 120 inch stick comes punched along the base rather than solid. That lets you bolt the channel flat to a wall, deck or beam without field drilling, and gives some adjustment along the slot for lining up a run. If you want an unpunched back for a cleaner look or full section strength, you want a solid-back B12 instead of the SH version.

Each 120 inch stick weighs 23.9 pounds. That is a one-man carry for a single length but a two-man lift once you bundle three or four, and it matters when you are calculating the dead load of a long overhead trapeze run before you size the rod and anchors.

The channel ships as bare 120 inch stock. You still need the hardware: strut nuts sized for the 1-5/8 inch opening (spring nuts for overhead work so they hold position while you start the bolt), hex bolts and washers, threaded rod and rod couplings or beam clamps for overhead drops, and post bases or wall brackets where the run lands. Conduit or pipe clamps are separate again. Standard 1-5/8 inch strut fittings fit this channel because the width is the common 1.62 inch opening.

Order Eaton B-Line part B12SH-120GLV. Reading the number: B12 is the deep channel section, SH is the slotted hole back, 120 is the length in inches, and GLV is the pre-galvanized finish. That is the number to quote if you are matching stock already on the job.

Yes. Two B12 sections welded or bolted back to back give you a box section for long spans and heavy racks, and because the profile is a consistent 2.43 by 1.62 inches, both faces line up and standard strut nuts still work in each open side. If you are building that assembly, plan on it doubling the 23.9 pound per stick dead load in your hanger calculations.
