B-Line Eaton series strut channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, K06 Hole pattern, B52 channel type,

The B52 is a half-height channel. It measures .81 in high by 1.62 in wide, so it gives you the standard 1-5/8 inch strut face width with roughly half the depth of full-height 1-5/8 x 1-5/8 channel. That matters where you are tight to a ceiling or wall and cannot give up 1-5/8 inches of projection, but it also means less load capacity than full-height channel of the same gauge.

Yes. The channel face is 1.62 in wide, which is the standard 1-5/8 inch strut opening, so spring nuts, channel nuts, clamps, post bases and fittings sized for 1-5/8 inch strut engage the return lips normally. What will not carry over is anything that depends on channel depth, like back-to-back or deep-section brackets, since the section is only .81 in tall.

K06 is a knockout pattern punched in the back of the channel, so you are not drilling the base to anchor it. You pick up fasteners through the existing openings rather than laying out holes on site. The slotted face of the channel still takes strut nuts anywhere along the 240 in run, so the hole pattern only affects how you fix the back of the channel to structure.

Pre-galvanized is the finish here, and it is a mill-applied zinc coating on the steel before forming. That makes it suitable for indoor and normally dry commercial and industrial work. Cut ends and punched edges are left bare after fabrication, so for exposed exterior, coastal, wash-down or chemical areas you want hot-dip galvanized after fabrication or stainless instead of this pre-galv B52.

12 gauge steel is the standard structural thickness for strut channel and is what most conduit racking, trapeze hangers and equipment supports are built from. On this B52 the trade-off is the section, not the metal: at .81 in high it carries less than a full-height 1-5/8 x 1-5/8 12 gauge channel over the same span, so use it for shorter spans, wall-mounted runs and light-to-moderate loads and step up to full-height channel for long unsupported trapeze spans.

Order it as Eaton B-Line B52KO6-240GLV. Reading the code: B52 is the half-height channel section, KO6 is the knockout hole pattern, 240 is the length in inches, and GLV is the pre-galvanized finish. If you need a different length or a solid-back channel, only the middle and trailing segments of that number change.

Yes, steel channel this gauge cuts with a bandsaw, chop saw with a metal blade, or portaband. Because the finish is pre-galvanized, the cut end is bare steel, so hit it with cold galvanizing compound if the run is anywhere humid or exposed. The knockout pattern in the back means you should check where your cut falls relative to the openings so you still have anchoring points where you need them.
