B-Line Eaton series strut fittings and accessories, 3.43" Height, 12" Length, 1.62" Width, 1.43lbs, Steel, Left bracing slotted bracket, Thickness 1/4

It's the left-hand version. B-Line part B178SHLGRN is a left bracing slotted bracket, so the slot pattern and bend run one way only. If your brace angles off to the opposite side of the strut run, you need the right-hand mate instead. On a job with braces going both directions, order both hands.

Six holes total: one 7/16 inch diameter round hole, and four slots measuring 1 inch long by 13/32 inch. The 7/16 inch hole takes standard 3/8 inch strut hardware, and the slots give you adjustment along the length when the brace angle or hole spacing isn't exact.

The bracket measures 12 inches long, 3.43 inches high and 1.62 inches wide. That 1.62 inch width matches the face of standard 1-5/8 inch channel, so it sits flat on the strut face rather than overhanging it.

Quarter-inch steel. That's the same gauge B-Line uses on its heavier bracing fittings, and it's why the bracket weighs 1.43 lb at only 12 inches long. For trapeze or seismic bracing work where a formed light-gauge bracket would deflect, the 1/4 inch plate is the reason to pick this one.

No fasteners are included with the bracket itself. Plan on strut nuts and bolts sized to the 7/16 inch hole and the 13/32 inch slots, which means 3/8 inch hardware, plus whatever anchors the structural attachment calls for.

DURA GREEN is Eaton B-Line's coated finish for steel strut fittings, applied over the 1/4 inch steel here. It's the standard painted-type finish you'll see across B-Line channel systems, so it matches green-finished strut and fittings already on a run. For continuously wet or corrosive locations, spec a hot-dip galvanized or stainless fitting instead.

The B178SHLGRN left bracing bracket is supplied as a plain steel structural fitting with no listing marked against it. If your drawing calls for a certified seismic bracing component with an evaluation report, confirm the specific listed part number your engineer specified rather than substituting this one.
