B-Line B52SH-240GRN Eaton series strut channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, SH hole pattern, B52 channel type, DURA GREEN

12 gauge steel is the standard commercial strut thickness for conduit racks, trapeze hangers, and equipment supports. Keep in mind this is the .81 in deep B52 half-height profile, not a full-depth channel, so its span and load capacity are lower than 1-5/8 x 1-5/8 strut at the same gauge. For long unsupported spans or heavy pipe, step up to the full-height channel or shorten the support spacing.

SH is the slotted-hole pattern, punched through the back of the channel rather than left solid. It lets you through-bolt the channel to structure, beams, or wall anchors anywhere along the run without drilling on site, and the slots give you some adjustment to line up with existing anchor spacing. If you want an unpunched back, that's a different pattern designation on the B52 channel.

DURA GREEN is Eaton B-Line's green coating applied over the 12 gauge steel channel. It's a painted/coated finish, so it suits dry interior and protected mechanical and electrical spaces. For continuous outdoor exposure, corrosive process areas, or wet locations, specify a hot-dip galvanized or stainless channel instead rather than relying on a coated finish.

Order B-Line part number B52SH-240GRN. The code breaks down as B52 channel profile, SH slotted hole pattern, 240 inch length, GRN for the DURA GREEN finish. Changing any one of those changes the part number, so confirm the suffix matches the finish and punch your spec calls for.
