B-Line B134RZN Eaton series strut fittings and accessories, 3.5" Height, 3.93" Length, 1.87" Width, 1.00lbs, Steel, Four hole gussetted corner angle, 90 deg | Right hand, Thickness 1/4 in, Electro-plated

The B134RZN is the right hand version. Handing matters on a gussetted corner angle because the gusset sits on one side of the corner only, so a right hand piece and a left hand piece are mirror images and are not interchangeable if the gusset has to clear something. If your corner needs the gusset on the opposite face, you want the left hand part instead.

It measures 3.5 inches height, 3.93 inches length/depth, and 1.87 inches width, with 1/4 inch material thickness, and weighs 1 lb. The 1.87 inch width is the figure to check against your strut face, and the 3.5 and 3.93 inch leg dimensions tell you how far the bracket reaches down each member, which decides whether the bolt holes clear an adjacent fitting or a wall.

The B134RZN carries an electro-plated (zinc) finish, which is a thin coating intended for dry indoor use. For exterior, damp, or corrosive environments, specify a hot dip galvanized or stainless version of the same fitting rather than the electro-plated one.

No. The B134RZN ships as the steel bracket alone. You order the hardware separately, typically channel nuts with a spring and hex head bolts sized to the strut you are connecting, four sets per fitting to use all four holes.

Order it as Eaton B-Line B134RZN. The ZN suffix is the electro-plated zinc finish and the R designates the right hand configuration.

Use the gussetted type, like the B134RZN, where the joint takes real load or racking, such as a cantilevered pipe support or a trapeze leg. The gusset triangulates the corner so the connection resists bending rather than pivoting on the bolts. A plain flat 90 degree angle is fine for light alignment work or where the gusset would foul an adjacent member, but it depends on fastener shear and is the weaker joint.

Certifications are shown as Not Applicable for the B134RZN. It is a structural steel strut fitting, not an electrically rated device, so the specs that govern its use are the material and thickness, 1/4 inch steel, rather than a listing mark.
