B-Line B494-30SS4 Eaton series strut fittings and accessories, 11.25" Height, 30" L, 1.62" W, 8.85lbs, Steel, Braced single bracket, Load capacity 1600 lbs, Bottom brace: B42 on B494-24 and smaller and B22 on B494 and up, Stainless steel type 304

The B494-30SS4 braced single bracket is rated for 1,600 lbs load capacity. It's a braced design, meaning the diagonal brace ties back to the strut run to carry the cantilever moment rather than relying on the channel nuts alone. Use that 1,600 lb figure as the bracket's published capacity; the anchors and the strut it mounts to still have to be sized for the same load.

It gives 30 inches of arm length, with an 11.25 inch height for the brace leg and a 1.62 inch width. So you get a 30 inch cantilevered shelf off the strut, and you need roughly 11-1/4 inches of clear strut below the arm connection for the brace to land.

On the B494-30, the bottom brace is B22 channel. B-Line specifies B42 brace channel on B494-24 and smaller, and B22 on B494 and up, so the 30 inch version falls in the B22 group. Order the brace channel to match if it isn't supplied with the arm.

Yes. The SS4 suffix means Type 304 stainless steel, so it holds up outdoors, in wet process areas, food plants, and coastal installs where plain or pre-galvanized steel would rust at the cut edges. Pair it with 304 stainless strut, nuts, and bolts so you don't set up galvanic corrosion at the connections.

A plain (unbraced) bracket resists the load only through the bolted connection at the channel, so its capacity drops fast as the arm gets longer. The B494 is a braced single bracket: a diagonal brace runs from the outer end of the 30 inch arm back down to the strut, turning the cantilever into a triangle. That's why it carries 1,600 lbs at a 30 inch projection. If you only need a few inches of stand-off for a small conduit run, an unbraced knee bracket is simpler and cheaper.

Yes. The manufacturer part number is B494-30SS4, from Eaton's B-Line series strut fittings and accessories line. The base B494 is the braced single bracket, -30 is the 30 inch arm, and SS4 designates Type 304 stainless.

Each bracket weighs 8.85 lbs. That's a one-man lift for a single unit, but on an overhead run with brackets on repeated centers the dead load adds up, so count it into the total when sizing your anchors and the supporting structure.

It's a strut fitting used to build cantilevered supports off a wall-mounted or column-mounted strut run: cable tray, conduit racks, pipe runs, and equipment shelves. The 30 inch arm suits multi-tier tray or several conduit runs stacked on one arm, and the stainless construction makes it common in plants, tunnels, and exterior racks.
