B-Line Eaton series strut fittings and accessories, 1.87" Height, 1.62" Length, 2.40" Width, .58lbs, Steel, Two hole bus duct clevis, Electro-plated z

It's a two hole bus duct clevis, the fitting that wraps the bus duct hanger rod connection and ties the duct run back to a strut or threaded rod support. Two holes means it takes a through-bolt on each side of the clevis rather than a single pin, so the duct is captured between both legs. It's part of the Eaton B-Line strut fittings and accessories line, so it works within a standard strut and rod support system.

It's steel with an electro-plated zinc finish, which is the standard indoor/dry-location protection on strut hardware. Electroplated zinc gives corrosion resistance for interior mechanical and electrical rooms, not sustained weather exposure. For exterior runs, a wash or roof deck, specify a hot dip galvanized or stainless equivalent instead.

Order Eaton B-Line part number B408-1ZN. The ZN suffix is the electro-plated zinc finish. It's a single configuration, so there is no handing, size or finish selection to make on the order.

The B408-1ZN is the clevis body only, supplied as a single steel fitting weighing .58 lb. Plan on ordering the through-bolts, nuts and threaded rod separately, along with whatever strut channel or rod attachment carries the load above it.

No certification applies to this fitting. It's a mechanical support component in Eaton's B-Line strut accessory line, and support hardware of this kind is specified by the engineer's hanger detail rather than by a product listing. If your submittal requires a listed assembly, that requirement will sit with the bus duct itself.
