B-Line B293A-12GRN Eaton series strut fittings and accessories, 3.5" Height, 12" Length, 1.62" Width, 2.52lbs, Steel, Number of mounting holes (1) 9/16 in diameter (vertical), Bracket, channel opening downward, Uniform load capacity 600, DURA GREEN

The B293A-12GRN is a steel strut bracket that mounts with the channel opening facing downward, so the strut nut and bolt load into the channel from below. It measures 12 inches long, 3.5 inches high and 1.62 inches wide, and it's the piece you use where a run of strut has to be picked up off a wall or beam face and the attachment hardware needs to come up into the channel rather than down into it.

There's one mounting hole, 9/16 inch diameter. That clears a 1/2 inch bolt, anchor or threaded rod with room to spare, which is the standard strut hardware size. The 9/16 hole is the only fastening point on the bracket, so whatever you anchor into needs to carry the load through that single connection.

Uniform load capacity is rated at 600 on the B293A-12GRN. Because everything transfers through a single 9/16 inch hole, the anchor and the base material you're fastening into will usually govern the real-world limit, not the bracket steel.

No. The bracket ships as the bracket only. You supply the channel nut, bolt and washer for the strut connection, plus the 1/2 inch anchor or bolt through the 9/16 inch hole. Order those separately with the strut.

It comes down to which way you can get a wrench. The B293A-12GRN presents the channel slot facing down, so the nut spins in from underneath, which is what you want when the bracket is mounted high and you're working below it. An upward-opening bracket gives you the slot from the top, better for floor-level or platform mounting where you're reaching down. Same load path, different access, so pick by where the installer will be standing.

Order Eaton B-Line part number B293A-12GRN. The B293A is the bracket series, the -12 is the 12 inch length, and GRN is the DURA GREEN finish. Same bracket in a different length or finish will carry a different suffix, so match the full designation when standardizing a job.

DURA GREEN is Eaton B-Line's coated finish on this steel bracket, and it's the finish to specify when you want something more than plain mill steel in mechanical rooms, parking structures and similar service areas. For continuously wet or chemically aggressive locations, specify a hot-dip galvanized or stainless version of the same bracket instead.

It weighs 2.52 lb, light enough to set and hold one-handed on a ladder while you start the anchor. That also matters when you're adding up dead load on a long overhead strut run made up of many of these.

No certification applies to the B293A-12GRN. It's a mechanical support bracket, so where a project spec calls for a listed support assembly, that listing sits with the strut system and the anchors rather than with the bracket itself.
