B-Line Eaton series strut fittings and accessories, 4.20" Height, 3.5" Length, 1.62" Width, 1.00lbs, Steel, Four hole gussetted corner angle, 90 deg |

The B134LGRN is the left hand version of the four hole gusseted 90 degree corner angle. Handing refers to which side the gusset and hole pattern face once the fitting is set against the strut, so a left hand and right hand fitting are mirror images, not interchangeable. If your joint needs the gusset on the opposite face, order the right hand part instead.

No. The four hole gusseted corner angle is the bracket only. You supply the channel nuts and hex head bolts for all four holes, sized to the strut channel you are building with. Order those separately when you spec the fitting so the crew is not short of hardware at the joint.

DURA GREEN is B-Line's coated steel finish, applied over a steel body. It is the corrosion-resistant option B-Line uses in place of plain or electro-galvanized parts, so it is the choice when the run is exposed to moisture, wash-down, or a corrosive plant environment rather than a dry interior ceiling space. Match the fitting finish to the strut channel finish so you are not mixing coatings at the joint.

The fitting measures 4.2 inches in height, 3.5 inches in length/depth, and 1.62 inches in width, and it weighs 1 pound. The 1.62 inch width is the figure to check first: it is sized to sit on standard strut channel face, so confirm the channel width you are fastening to before ordering a stack of them.

Use the gusseted angle where the corner carries real load or where deflection at the joint matters. The gusset ties the two legs together so the 90 degree relationship holds; a plain flat angle relies only on the bolts and the fitting's own stiffness and can flex. For light-duty bracketing or where clearance behind the joint is tight, a plain angle is the simpler pick.

A single left hand fitting will make a corner, but on framed strut assemblies corners are commonly doubled up with one fitting on each face so the load is shared and the joint is square in both directions. If you are building that way, count left hand and right hand parts in equal quantity for each corner.
