B-Line B198A-12ZN Eaton series strut fittings and accessories, 3.5" Height, 12" Length, 1.62" Width, 2.84lbs, Steel, Clevis bracket, channel opening downward, Uniform load capacity 800 lbs, Electro-plated

The B198A-12ZN carries a uniform load rating of 800 lbs. That is a uniform load across the 12 inch member, not a point load at the free end, so keep the hung weight distributed and centered rather than concentrated at the tip.

Channel opening faces downward on the B198A-12ZN. That matters when you plan the run: spring nuts and strut clamps load into the open side from below, so pipe, conduit or trapeze hardware attaches under the arm rather than on top of it. If you need the channel facing up so hardware sits above the bracket, this is not the part.

Yes. At 1.62 inches wide the channel is the common 1-5/8 inch strut section, so spring nuts, pipe straps, conduit clamps and beam clamps built for 1-5/8 channel engage it normally. Because the opening faces down, load the nuts from underneath.

Electro-plated zinc is a light indoor-duty coating. It holds up in dry interior mechanical rooms, ceiling spaces and conditioned plant areas. For exterior runs, parking structures, wash-down areas or anywhere with regular condensation, specify a hot dip galvanized or stainless version of the fitting instead, because a plated finish will surface rust in those conditions.

A clevis bracket like the B198A-12ZN cantilevers a single point of support out from a wall, beam or column, with the channel opening down so your clamps hang beneath. Use it where you only have one structural face to anchor to. A trapeze needs two threaded rods dropped from the deck and is the better choice for multiple parallel runs or heavier aggregate loads. Where the run is a single conduit or pipe coming off a wall, the bracket is fewer pieces and less rod.

The B198A-12ZN is supplied as the steel bracket alone. Anchors or bolts for fastening it to the structure, and the spring nuts, straps or conduit clamps for attaching to the channel, are ordered separately. Plan the anchor to the base material you are fixing into, since that fastener, not the bracket, usually sets the real capacity of the assembly.

Order it as B198A-12ZN, an Eaton B-Line series strut fitting. The ZN suffix indicates the electro-plated zinc finish and the 12 corresponds to the 12 inch length.
