B-Line B54SH-240GRN Eaton series strut channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 14 Gauge, SH hole pattern, B54 channel type, DURA GREEN

B54 is the shallow profile. It measures .81 in in channel height against a 1.62 in channel width, so it's roughly half the depth of a standard 1-5/8 x 1-5/8 strut. Use it where you need a low-profile run tight to a wall, ceiling deck, or inside a furred space. If you're hanging heavier trapeze loads or want full-depth nut engagement, go to a full 1-5/8 in deep channel instead.

Yes on the opening dimension. B54 runs 1.62 in wide, the standard 1-5/8 in strut width, so common spring nuts, channel nuts, and fittings sized for 1-5/8 in strut engage the lipped opening. Watch the depth, though: at .81 in tall there is less interior room than a full-depth channel, so tall-bodied or long-spring nuts and some deep fittings won't seat. Short-spring or no-spring nuts are the safe pick.

SH is the slotted-hole back pattern, so the channel arrives pre-punched along the base rather than solid. That lets you bolt it directly to studs, deck, or concrete without field drilling, and the slots give you some adjustment along the run. If you want an unpunched back for a cleaner look or continuous strength, you'd be ordering a plain (non-SH) B54 instead.

DURA GREEN is B-Line's green painted coating over the 14 gauge steel channel. It's a coated-steel finish, which suits dry interior mechanical and electrical spaces. For wet, corrosive, or exterior exposure you'd specify a hot dip galvanized or stainless channel rather than a painted one.

Order B-Line B54SH-240GRN. The suffix breaks down as B54 channel type, SH slotted back, 240 in length, GRN for the DURA GREEN finish. It's a single configuration, so there are no finish or length options to select alongside it.

Mechanically, yes. B54SH shares the 1.62 in channel width used across the strut system, so the same nuts, brackets, and clamps carry over regardless of finish. The visible difference is cosmetic, DURA GREEN paint versus a galvanized run. If the installation is exposed and the owner cares about appearance, standardize on one finish across the openings you can see.
