Product DescriptionThe ABB B-917 is a five-hole angle connector designed for structural strut and beam connections in electrical, mechanical, and plumbing support applications. Formed from steel, this L-shaped bracket measures 4.5 inches in overall length with a 3-inch leg extending from the beam face and a 1.5-inch width. The five mounting holes are 9/16 inch in diameter and spaced on 1.5-inch centers, conforming to standard strut channel hole patterns. Electricians, pipefitters, and mechanical contractors use this connector to join unistrut-style channel sections at right angles in rigid support assemblies.The B-917 is suited for residential and commercial installations where strut channel framing is used to support conduit, pipe, duct, or equipment. It is a common component in electrical panel support structures, mechanical room pipe racks, and overhead cable tray systems. The angle bracket allows secure perpendicular connections between strut members and beam flanges or structural steel.Key FeaturesFive 9/16-inch holes on 1.5-inch centers for compatibility with standard strut channel hole spacing4.5-inch overall length with a 3-inch beam leg for extended reach and solid bearing surface1.5-inch width matches standard strut channel profileSteel construction for strength and durability in typical indoor support applicationsAngle design enables right-angle connections between strut sections and structural membersCompatibilityDesigned as an OEM-style fitting for use with standard 1.5-inch strut channel framing systems in electrical and mechanical support assemblies.Installation NotesInstallation is typically performed by licensed electricians or mechanical contractors as part of a strut channel support system. Ensure all support structure is de-energized and secured before beginning work in live electrical or mechanical spaces. Hardware such as carriage bolts, spring nuts, and strut washers appropriate for the channel type should be sourced separately. Installations must comply with applicable NEC or IPC support spacing requirements for the system being supported.Technical SpecificationsOverall Length: 4.5 inchesLength from Beam: 3 inchesWidth: 1.5 inchesHole Diameter: 9/16 inchHole Spacing: 1.5-inch centersNumber of Holes: 5Material: SteelUPC: 785991757620Standard InformationBrand: ABBManufacturer Part Number: B-917
