B-Line B494-42ZN Eaton series strut fittings and accessories, 16" Height, 42" L, 1.62" W, 12.85lbs, Steel, Braced single bracket, Load capacity 1285 lbs, Bottom brace: B42 on B494-24 and smaller and B22 on B494 and larger, Electro-plated zinc

The B494-42ZN braced single bracket is rated for 1285 lbs load capacity. That rating assumes the bracket is properly anchored to structure and the bottom brace is installed as specified; the brace is what carries the moment on a 42 inch cantilevered arm.

The B494 bracket family uses a B42 bottom brace on B494-24 and smaller, and a B22 brace on B494 and larger. Since the B494-42ZN is a 42 inch arm, plan on the larger-size brace called out in that schedule. The brace is a separate strut piece, so order it along with the bracket and your fasteners.

It measures 42 inches long, 16 inches high, and 1.62 inches wide, and weighs 12.85 lbs. The 16 inch height is the vertical leg that bolts back to your strut or wall, and the 1.62 inch width matches standard 1-5/8 inch strut so it lines up with a B-Line channel run.

Electro-plated zinc is the finish here, and it's a indoor, dry-location coating. For rooftops, parking structures, wash-down areas, or anything exposed to weather or chemicals, step up to a hot-dip galvanized or stainless version of the bracket instead. Zinc plating in those environments will show rust at the cut edges and bolt holes first.

A braced single bracket is a cantilever arm with a diagonal brace running from the outboard end back down to the vertical, so the load path goes into compression in the brace instead of pure bending in the arm. On a 42 inch arm like the B494-42ZN, that brace is what gets you to a 1285 lb rating. An unbraced shelf bracket of the same length would carry a fraction of that. Use the braced version for pipe racks, cable tray runs, conduit banks, and equipment shelves where the load sits well out from the wall.

The B494-42ZN is the steel bracket itself. The bottom brace channel, the channel nuts and bolts joining brace to bracket, and the anchors into your wall or structure are separate items. Budget for the brace length called out for this size plus the fastener kit when you write the order.

Yes. The bracket's 16 inch vertical leg is punched for channel-nut attachment and its 1.62 inch width matches 1-5/8 inch strut, so it bolts to a vertical strut post or back-to-back column the same way it bolts to a wall-mounted channel run. Mounting to a strut column is common where you need multiple tiers at different elevations off one upright.

Order it as B494-42ZN. B494 is the braced single bracket series, 42 is the arm length in inches, and ZN designates the electro-plated zinc finish. Other lengths in the same series carry the same B494 prefix with a different length suffix.
