B-Line B409-24HDG Eaton series strut fittings and accessories, 4.62" Height, 24" Length, 1.62" Width, 4.50lbs, Steel, Single channel bracket, Uniform load capacity 480 lbs, Hot-dipped galvanized

The B409-24HDG carries a uniform load capacity of 480 lbs. That is a uniform load across the bracket, not a point load at the free end, so distribute conduit runs, cable tray supports, or pipe clamps along the 24 inch length rather than hanging everything off the tip.

Yes. The B409-24HDG is steel with a hot-dipped galvanized finish, which is the finish specified for exterior, damp, and corrosive-environment strut work such as rooftops, parking structures, and wastewater plants. For dry interior runs, the plain or electro-galvanized version of the same bracket is the usual pick.

It measures 24 inches long, 4.62 inches high, and 1.62 inches wide, and weighs 4.5 lbs. The 1.62 inch width is the standard 1-5/8 inch strut channel profile, so it sits flush against 1-5/8 inch strut and takes standard strut nuts and hardware.

The B409-24HDG is sold as the bracket alone. Budget separately for strut nuts, hex bolts, and washers in a matching hot-dipped galvanized finish, plus anchors for the wall or structural attachment. Mixing a plain steel fastener into a hot-dipped galvanized assembly outdoors will rust at the fastener first.

A single channel bracket like the B409-24HDG is a one-piece length of channel with mounting holes, fixed to a wall, column, or ceiling to create a cantilevered or braced support for conduit, cable tray, pipe, or equipment. At 24 inches it gives a long arm for multiple conduit runs off one wall attachment. Where you need the load carried in two planes or a right-angle connection between channel runs, an angle fitting or post base is the fitting to use instead.

Yes. Order it as Eaton B-Line B409-24HDG. That single manufacturer part number covers the 24 inch hot-dipped galvanized single channel bracket, so it is the number to standardize on across a facility or repeat spec.
