The ABB B921 is a two-side corner connector designed for use in Kindorf channel and strut framing systems. This fitting creates a rigid right-angle connection between two runs of channel, maintaining structural integrity at corners in electrical support, conduit support, and mechanical equipment framing installations. The B921 is typically installed by electricians and mechanical contractors working on commercial, industrial, or utility projects where channel framing is specified for equipment support or cable tray systems. Each outer pack contains 20 connectors.
The B921 is suited for commercial and industrial applications where Kindorf-style channel strut is used to construct support frames, trapeze hangers, equipment racks, and similar structural assemblies. It is commonly found in electrical rooms, mechanical rooms, and open ceiling installations where rigid corner connections are required to maintain frame alignment and load distribution across the strut grid.
Designed as an OEM-style fitting for use with standard Kindorf channel strut framing systems in commercial and industrial installations.
Installation is typically performed by licensed electricians or mechanical contractors following applicable NEC and local building code requirements for support structures. De-energize all nearby electrical equipment before working in the installation area. Use appropriate fasteners rated for the intended load; do not exceed the structural load ratings of the channel system. Inspect all channel runs and connectors for proper seating and secure fastener engagement before placing the assembly into service.
