B-Line B104SHZN Eaton series strut fittings and accessories, 4.12" Height, 4.12" Length, 1.62" Width, .78lbs, Steel, Pre-assembled fitting, Three hole adjustable corner angle, 90 deg, Electro-plated

It's a three hole adjustable corner angle for strut framing, set up for 90 degree connections. You use it where two runs of strut meet at a corner and you need the leg angle to move rather than sit fixed. Each leg carries holes for strut nuts and bolts, and it ships pre-assembled so the pivot hardware is already in place.

The B104SHZN is listed as a pre-assembled fitting, meaning the two legs come joined with the pivot hardware already fitted. The channel nuts and bolts that fasten the angle to your strut are separate hardware and should be ordered with the fitting to match your channel size.

It's steel with an electro-plated (zinc) finish, which is a general indoor, dry-location coating. For wet exterior work, washdown areas or corrosive environments, specify a hot dip galvanized or stainless version of the same corner angle instead.

Use the adjustable three hole corner angle like the B104SHZN when the two members meet at a corner and you want to set or fine tune the angle on site, or when field conditions are not perfectly square. A fixed 90 degree angle bracket is the better pick when the joint is truly square and you want the bracket itself to hold the angle without relying on bolt torque.

Yes. It's an Eaton B-Line series strut fitting, ordered under manufacturer part number B104SHZN, so it belongs to the same accessory family as the rest of the B-Line channel hardware you'd already be running on the job.
