B-Line Eaton series slotted angle, 1.58" height, 2.25" length, 1.58" width, Steel channels, Green, Dura green, 12 gauge, Channel, strut and fittings,

Yes, the SA318GRN144 carries a UL Listing. For an inspector on a commercial or institutional job, that is the line item that matters when the support hardware is part of an electrical raceway or equipment support assembly.

Order Eaton B-Line part number SA318GRN144. That single model covers the 12 gauge Dura Green single piece (up) beam section; there are no other finish or size options under that number.

It is a single piece (up) beam section of slotted angle, used with steel channel and strut systems to build supports, racks, and framing for electrical work. Being slotted, it bolts to strut and fittings without drilling, so you cut to length and assemble rather than fabricate.

12 gauge steel. That is the heavier end of the strut-and-angle range, which is what you want when the angle is carrying a load rather than just aligning parts.

The SA318GRN144 comes in B-Line's Dura Green finish, a green coated steel finish rather than bare or plain steel. It is a coated product intended to resist corrosion in service, but it is not a hot-dip galvanized or stainless part, so for continuous wet, chemical, or outdoor marine exposure you should specify a galvanized or stainless angle instead.

Only if the existing material is B-Line's Dura Green. Green coated strut and green painted strut from other lines are not the same coating, and the shade will read differently side by side. If your building is standardized on plain, pre-galvanized, or hot-dip strut, order the matching finish rather than this green one.

No. It is the beam section on its own. Hardware to join it to strut, channel nuts, and any fittings or brackets are ordered separately, so build your list of connectors before the angle goes on the truck.
