B-Line B179SHLZN Eaton series strut fittings and accessories, 3.93" Height, 14" Length, 1.62" Width, 1.62lbs, Steel, Left bracing slotted bracket, Thickness 1/4 in, Electro-plated

The B179SHLZN is a left bracing slotted bracket from the Eaton B-Line strut fittings line. It ties a diagonal brace back to a strut run to triangulate the assembly, which is what stops a cantilevered or trapeze support from swaying. Because it is a left-hand bracing bracket, a run braced in the opposite direction needs the right-hand version instead.

It is the left-hand version. Handing matters on bracing brackets because the slot pattern and the angle of the leg only line up when the brace runs the intended direction; install a left bracket where a right is called for and the bolt holes will not land on the strut. Confirm the brace direction on your layout before ordering quantities.

Six holes total: one 7/16 inch diameter round hole and four slots 1 inch long by 13/32 inch. The 7/16 inch hole and the 13/32 inch slots both take 3/8 inch bolts, which is the usual strut hardware size, and the 1 inch slot length gives you adjustment to pull the brace into position before tightening.

It measures 14 inches in length/depth, 3.93 inches in height, and 1.62 inches in width, formed from steel at 1/4 inch thickness. The 1.62 inch width matches standard 1-5/8 inch strut face, so it sits flush on a 1-5/8 inch channel. Shipping weight of the piece is 1.62 lb.

The finish is electro-plated zinc over steel, which is a dry indoor finish. It holds up in conditioned mechanical rooms, ceiling spaces, and electrical rooms, but for exterior, rooftop, or wash-down areas you want a hot-dip galvanized or stainless bracing bracket instead.

No hardware is included. The bracket ships as the steel bracing member only, so plan on 3/8 inch strut nuts and bolts for each of the mounting points, six per bracket if you fasten through every hole.
