B-Line B409-18HDG Eaton series strut fittings and accessories, 4.62" Height, 18" Length, 1.62" Width, 3.47lbs, Steel, Single channel bracket, Uniform load capacity 640 lbs, Hot-dipped galvanized

The B409-18HDG is rated for a 640 lb uniform load. That is a uniformly distributed rating across the 18 inch bracket, not a point load at the free end, so keep concentrated loads well under it and mount the bracket to strut with the correct channel nuts and bolts for the run.

Yes. The B409-18HDG is steel with a hot-dipped galvanized finish, which is the finish specified for outdoor, damp, and washdown locations where a plain or electro-galvanized bracket would rust. Pair it with hot-dipped galvanized strut and hardware so you are not mixing finishes on the same connection.

It measures 18 inches long, 4.62 inches high, and 1.62 inches wide, and weighs 3.47 lb. The 1.62 inch width is the standard 1-5/8 inch strut profile dimension, so it sits flush against 1-5/8 inch channel. Use the 18 inch length to confirm your cantilever reach clears conduit, duct, or pipe before you order.

A single channel bracket like the B409-18HDG is a length of strut section pre-punched and formed to bolt onto an existing run, giving you a cantilever arm or a right-angle extension off the main member. It is what you use to hang conduit racks, cable tray, or small equipment off a wall or column without fabricating a whole second run of strut. For heavier or longer reaches you would step up to a double channel bracket instead.

Yes, the B409-18HDG is supplied as the bracket alone. Bolts, channel nuts, and any anchors for fastening to concrete or steel are ordered separately. Specify hot-dipped galvanized hardware to match the bracket finish in exterior work.

Order it as B409-18HDG from Eaton's B-Line series. The B409 is the single channel bracket family, the 18 is the 18 inch length, and HDG designates the hot-dipped galvanized finish. That suffix matters on a submittal, since the same bracket exists in other finishes.
