B-Line Eaton series strut channel, .81" channel height, 120" channel length, 1.62" channel width, Steel, 12 Gauge, S hole pattern, B52 channel type, P

The B52 is the shallow one. It measures .81 inch high by 1.62 inch wide, so it's the half-height profile with a standard 1-5/8 inch face. Use it where you need the strut face width for standard strut nuts and fittings but don't have the depth for a full 1-5/8 x 1-5/8 channel, such as tight ceiling plenums or wall furring runs. For heavier trapeze loads or longer unsupported spans, step up to the full-depth profile instead.

Pre-galvanized is the finish here, which is a mill-applied zinc coating suited to dry indoor and protected areas. Cut ends and punched edges are bare steel, so it isn't the choice for exterior exposure, washdown, coastal air, or corrosive process environments. For those, specify hot-dip galvanized after fabrication or stainless strut.

Yes. The open face is 1.62 inch, the standard 1-5/8 strut opening, so channel nuts, spring nuts, pipe clamps, and conduit straps made for 1-5/8 strut engage the lips normally. The difference from full-depth strut is behind the face, not at it, so fittings carry over.

S is the slotted back pattern, meaning the web is punched with slots along the length rather than being solid. That lets you bolt through the channel back to structure anywhere along the run without field drilling. If you want an unpunched back for a cleaner look or maximum section, order the solid-back version of the B52 instead.

12 gauge steel, which is the common structural weight for strut channel and what most conduit racking, trapeze hangers, and equipment supports are built from. Because this is the .81 inch shallow profile rather than a full-depth section, keep support spacing tighter than you would with 1-5/8 x 1-5/8 strut on the same load.

Order Eaton B-Line B52S-120GLV. Reading the code: B52 channel type, S slotted hole pattern, 120 inch length, GLV for the pre-galvanized finish. Quote that number and you'll get the shallow 12 gauge steel channel and not the full-depth or solid-back variant.

No. It's bare channel only, a single 120 inch stick. Channel nuts, hardware, end caps, splice plates, post bases, and any brackets are ordered separately. Budget the fittings when you take off the job.
