B-Line B104YZN Eaton series strut fittings and accessories, 4.12" Height, 4.12" Length, 1.62" Width, .78lbs, Steel, Pre-assembled fitting, Four hole corner angle, 90 deg, pre-assembled, Yellow zinc chromate

The B104YZN is a four hole corner angle for strut channel, bent 90 degrees, used to tie two runs of strut together at a right angle. It ships pre-assembled, so the hardware comes with the fitting rather than being ordered separately. Two holes land on each leg of the angle.

No. It is supplied as a pre-assembled fitting, so the attaching hardware comes with it. What you still supply is the strut channel itself and any additional channel nuts you want for other connections on the run.

Yellow zinc chromate over steel is a plated finish meant for dry, indoor, protected work such as mechanical rooms, ceilings, and interior electrical support. It is not a hot-dip galvanized or stainless finish, so for exterior, wash-down, or corrosive environments choose a strut fitting in a galvanized or stainless version instead.

The part number is B104YZN, from the Eaton B-Line series of strut fittings and accessories. The YZN suffix is the yellow zinc chromate finish.

A four hole angle like the B104YZN puts two fasteners into each leg, which resists twist at the joint and is what you want on load-carrying corners and on braced overhead supports. A two hole angle, with one fastener per leg, can pivot under load and suits light bracket work or non-structural tie-ins. Its 4.12 inch legs give the bolt spread that makes the four hole version rigid.
