B-Line B297-42SS4 Eaton series strut fittings and accessories, 6.25" Height, 42" Length, 1.62" Width, 14.40lbs, Steel, Number of mounting holes (2) 9/16 in diameter (vertical), Bracket, Uniform load capacity 456 lb, Stainless steel type 304

The B297-42SS4 bracket is rated for a uniform load capacity of 456 lb. That is a uniform rating, so a concentrated point load at the free end of the 42 inch arm has to be evaluated against your own engineering allowance, not against this number directly.

Yes. The mounting holes in the B297-42SS4 bracket are 9/16 in diameter, which is the standard strut hole size and clears 1/2 inch hardware with room to adjust. Use 1/2 inch channel nuts and bolts to fasten it to the strut.

It is made from Type 304 stainless steel, so it handles washdown areas, rooftops, food processing and coastal exposure far better than plain or electro-galvanized strut hardware. For heavy chloride exposure such as pool chemical rooms or marine splash zones, Type 316 is the usual step up.

It measures 42 in in length, 6.25 in in height and 1.62 in in width. The 42 in dimension is the arm, so it reaches well out from the strut face, which is why the uniform load rating of 456 lb matters more here than on a short fitting. It weighs 14.4 lb, heavy enough that a second set of hands or a temporary support helps when you are bolting it up overhead.

It is a strut bracket, a fitting that bolts to channel to carry cable tray, conduit racks, pipe, or equipment out away from a wall or structural member. At 42 in it is a long-reach arm rather than a small corner or angle fitting, so it suits cantilevered tray and conduit runs where the load has to stand off the supporting steel.

Order Eaton B-Line B297-42SS4. The B297 is the bracket series, the 42 is the length in inches, and the SS4 suffix designates Type 304 stainless. If you need the same bracket in a different reach, the length digits change while the SS4 stainless suffix stays.
