B-Line B293-12ZN 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 upward, Uniform load capacity 600, Electro-plated

There is one mounting hole, 9/16 inch in diameter, oriented vertically. That clears a 1/2 inch bolt or anchor with room to spare. Hardware and anchors are not part of the bracket, so specify the fastener to suit whatever you are fixing into.

Uniform load capacity is rated at 600 for the B293-12ZN. Treat that as the uniformly distributed rating across the 12 inch arm, not a point load at the far end, and derate accordingly if your load is concentrated at the tip.

It is steel with an electro-plated zinc finish, which is an indoor and protected-environment coating. For exterior, wash-down, coastal or corrosive settings, step up to a hot-dip galvanized or stainless strut bracket instead, because electro-plate will rust once it is wet regularly.

Yes. The B293-12ZN is part of the Eaton B-Line strut fittings and accessories line and the arm is a section of 1-5/8 inch strut channel, 1.62 inches wide as specified, so standard 1-5/8 strut nuts, clamps and conduit straps drop into the upward-facing slot.

The B293-12ZN is a steel strut bracket with the channel opening facing upward, so it mounts to a wall or structure and gives you a 12 inch run of upward-facing channel to hang or clamp into. Typical use is supporting conduit, cable tray, pipe or equipment off a wall where you want the strut slot accessible from the top. It stands 3.5 inches high and 1.62 inches wide.

Order it as B293-12ZN. The ZN suffix is the electro-plated zinc finish and the 12 is the 12 inch channel length; the same B293 bracket family is built in other lengths, so the number after the dash is the one to check on a drawing.

Pick by where the load sits. The B293-12ZN opens upward, so fittings drop into the slot from above and the load is carried on top of the arm, which suits conduit runs, small pipe and trapeze-style supports where you want access from the top. A downward-opening bracket is the choice when you need to hang rod or clamps beneath the arm and keep the top face clear.

Each bracket weighs 2.52 lb. Add that to your hung load when you are totalling dead weight on an anchor or a structural member, especially if you are running a row of them along a wall.
