B-Line B181SHRZN Eaton series strut fittings and accessories, 4.93" Height, 18" Length, 1.62" Width, 2.32lbs, Steel, Right bracing slotted bracket, Thickness 1/4 in, Electro-plated

The B181SHRZN is a right bracing slotted bracket from the Eaton B-Line strut fittings line. It is the diagonal brace member used to triangulate a strut assembly, taking the sway out of a trapeze or wall-mounted run. It is the right-hand version, so if your brace angles the other way off the strut you need the left-hand equivalent instead. Steel, 1/4 in thick, with an electro-plated finish.

Overall it measures 18 in by 4.93 in by 1.62 in, with the 18 in dimension being the length of the brace leg. That is the working reach for laying out your brace angle between strut members. At 1.62 in wide it sits on standard 1-5/8 in strut channel face.

Six holes total: one 7/16 in diameter hole plus four slots that run 1 in long by 13/32 in. The 13/32 in slot width takes 3/8 in strut bolts, and the 1 in slot length gives you adjustment to set the brace angle without drilling. The single 7/16 in round hole is the fixed pivot point.

Often, yes. The B181SHRZN is the right bracing bracket. Braces are commonly run in opposing pairs to resist sway in both directions, so a symmetrical assembly needs the matching left-hand slotted bracing bracket alongside it. Check which way your brace leans off the strut before ordering quantities.

No. The B181SHRZN ships as the steel bracket alone, 2.32 lb. You supply the strut nuts and bolts to suit, 3/8 in hardware for the 13/32 in slots.

Electro-plated zinc is a dry-interior finish. It is fine for indoor mechanical rooms, ceilings and interior walls. For exterior, damp, or corrosive service, go to a hot-dip galvanized or stainless brace fitting instead, since electro-plating puts down a much thinner coating than hot-dip.
