B-Line Eaton series strut fittings and accessories, 2.25" Height, 2.25" Length, 1.62" Width, .41lbs, Steel, Two hole corner angle, 90 deg, no twist, E

The B231ZN is a two hole corner angle that joins two pieces of strut at a 90 degree corner. There is no twist in the fitting, so both bolt holes sit in planes that meet at a right angle, one hole into each strut leg. Use it where a horizontal run turns up or down into a vertical member and you want the channel faces square to each other.

The B231ZN is steel with an electro-plated finish. Electro-plated zinc is a thin coating suited to dry, indoor, conditioned spaces such as mechanical rooms, ceiling plenums, and electrical rooms. For wet, washdown, corrosive, or exterior work, step up to a hot dip galvanized or stainless version of the same fitting instead.

Yes. The B231ZN is the bracket only, a two hole steel corner angle. Each hole needs its own channel nut and hex head bolt (with the spring or no-spring nut style to suit how you are working overhead). Order the hardware to match the finish, electro-plated nuts and bolts with this electro-plated fitting, so you are not mixing coatings in the same joint.

No twist means the two legs of the B231ZN bend on the same plane, so the fitting ties strut faces that meet flat at 90 degrees. A twisted angle rotates one leg 90 degrees relative to the other, which is what you need when the two strut members run perpendicular but are mounted back to back or offset rather than face to face. Picking the wrong one leaves a bolt hole pointing the wrong direction and the connection will not draw up tight.

It measures 2.25 in height, 2.25 in length/depth, and 1.62 in width, and weighs .41 lb. That footprint keeps it inside the width of standard 1-5/8 inch strut, so it will not overhang the channel when you bolt it to the face. The light weight matters when you are pricing out a few hundred fittings for a trapeze job.

Order it as B231ZN, Eaton B-Line series. That is the manufacturer part number for the steel, electro-plated, two hole, no twist 90 degree corner angle.

No certification applies to the B231ZN. It is a mechanical steel strut fitting, so there is no rating attached to it; any listing requirement on the job applies to the raceway, cable, or equipment the strut is supporting, not to the corner angle itself.
