B-Line Eaton series strut fittings and accessories, 5.06" Height, 1.65" Length, 1.62" Width, .47lbs, Steel, Channel hanger, 16 gauge, Electro-plated

B241S-ZN is a steel channel hanger from the Eaton B-Line strut fittings and accessories line. It is a formed bracket that hangs strut channel from a structure, so the channel can then carry conduit, pipe, cable tray or equipment supports. It is a support fitting only, not a clamp or a strut length, so you order the channel and the threaded rod or anchors separately.

No, keep it indoors and dry. The finish is electro-plated zinc, which is a thin sacrificial coating meant for dry interior service. For exterior work, mechanical rooms with washdown, parking structures or coastal sites, specify a hot-dip galvanized or stainless strut fitting instead, otherwise you will see rust bleed at the formed edges and fastener holes.

The hanger is formed from 16 gauge steel, which is the gauge B-Line uses across its standard strut fitting line for interior conduit and pipe support work. For anything where a published load rating has to be shown on a submittal, size the run from the strut manufacturer's load tables for the channel and rod you are pairing it with, since the fitting is only one link in that assembly.

Order it by Eaton B-Line part number B241S-ZN. The B241S is the hanger itself and the ZN suffix is the electro-plated zinc finish, so if a spec or submittal calls out a different suffix it is the same fitting in another finish.

It will match other electro-plated (zinc) B-Line strut fittings, which is the standard interior finish, so it blends with existing plated channel and brackets. It will not match hot-dip galvanized parts, which are noticeably duller and heavier coated, and mixing plated steel against galvanized in a damp location is where you get accelerated corrosion. For fleet standardization, pick one finish per building area and stay with it.
