B-Line Eaton series strut fittings and accessories, 7.87" Height, 1.87" Length, 1.62" Width, 1.07lbs, Steel, One hole corner angle, Electro-plated zin

No. Electro-plated zinc is a thin indoor-duty coating. For outdoor, damp, wash-down or coastal work you want a hot dip galvanized or stainless version of the same corner angle instead. Using the plated part outside will show rust at the cut edges and bolt holes well before the strut does.

A single bolt per leg means the connection can pivot under load and relies on bolt clamping friction to stay square. For bracing, seismic work, or anywhere the joint takes moment, step up to a two or four hole angle or a gusseted bracket. The one hole version is for light, positional connections such as hanging small conduit runs, boxes, and light supports off strut.

The B420-778ZN measures 7.87 x 1.87 x 1.62 inches (height, length/depth, width) and weighs 1.07 lb. The 7.87 inch leg is the long dimension, so check your clearance behind the strut run before you order a stack of them for tight ceiling or wall cavities.

Hardware is not part of it. The corner angle ships as the steel bracket alone, so order channel nuts and hex head bolts sized to your strut separately, plus any spring nuts if you want them to hold position while you set the run.

Order by the manufacturer part number B420-778ZN. The ZN suffix is the electro-plated zinc finish; B-Line uses different suffixes for other finishes of the same body, so quoting the full number keeps you from getting a galvanized or plain steel bracket by mistake.
