Product DescriptionThe ABB H119C is a 3/8 inch square washer designed for use in electrical conduit and strut channel installations. Square washers distribute load more evenly than standard round washers, reducing the risk of pull-through on softer substrates and providing a larger bearing surface for nuts and bolts. Electricians and general contractors reach for this washer when securing conduit hangers, strut fittings, and similar hardware in both new construction and retrofit applications. The H119C is a straightforward, reliable fastener component suited to everyday commercial and industrial electrical work.This square washer is typically used in conduit support systems, cable tray installations, and unistrut or channel framing assemblies. It fits standard 3/8 inch fastener hardware and is well suited to panel and enclosure mounting, equipment anchoring, and general electrical rough-in work in residential, commercial, and light industrial settings.Key Features3/8 inch hole size fits standard 3/8 inch bolts and threaded rodSquare profile provides increased bearing surface compared to round washersCompatible with strut channel, conduit hanger, and framing hardwareSuitable for residential, commercial, and light industrial electrical installationsCompatibilityDesigned as an OEM-style replacement and general-use square washer for 3/8 inch fastener applications in electrical conduit support and strut channel framing systems.Installation NotesInstallation is typically performed by licensed electricians as part of conduit or strut support assemblies. De-energize any nearby circuits before working in electrical panels or enclosures. Use appropriate hand tools to torque fasteners to the hardware manufacturers recommendations. Follow applicable NEC guidelines for conduit support spacing and fastener requirements.Technical SpecificationsHole Size: 3/8 inchPackage Dimensions (L x W x H): 4.5 inches x 8.375 inches x 3.75 inchesPackage Weight: 11.5 poundsUPC: 78599178674Standard InformationBrand: ABBManufacturer Part Number: H119C
