B-Line Eaton series TOLCO sway brace attachment, Plain, 2015 lbs, Steel, Fig 4L, 6" pipe size, Longitudinal in-line sway brace attachment

The Fig 4L is the fitting that ties a sway brace into a run of pipe in the longitudinal direction, meaning it resists movement along the axis of the pipe rather than side to side. It installs in-line on the pipe itself, so the brace load transfers straight through the attachment into the pipe run. That makes it the piece you order when your seismic bracing layout calls for longitudinal restraint on a main; lateral restraint at the same point is a different attachment.

2015 lbs is the rated load capacity on the 6 inch Fig 4L. That is the number your engineer compares against the calculated longitudinal brace load at that point in the system. If the design load at the brace exceeds 2015 lbs, this attachment is not the right pick and the bracing point needs to be split or a heavier assembly specified.

Plain is bare, uncoated steel. It is the standard interior finish for sprinkler and pipe bracing components and it is what most concealed-space and conditioned-space installs use. For exterior work, a parking structure, or a wet or corrosive area, specify a galvanized version of the Fig 4L instead. Plain steel will surface rust in those conditions.

Allow for an 11.5 inch height on the 6 inch Fig 4L. That is the dimension to check against your tight spots, a joist pocket, a duct running alongside the main, or a ceiling grid close above the pipe. Worth confirming on the drawing before the pipe goes up, since the attachment clamps onto the pipe in-line and the brace leg comes off it.

Order Eaton B-Line series TOLCO part number FIG 4L 6 PLN. That designation breaks down as the Fig 4L longitudinal attachment, 6 inch pipe size, plain finish. Distributors matching against a submittal should use that MPN, since the same Fig 4L figure number covers a range of pipe sizes and finishes.

What you are buying is the attachment itself, the longitudinal in-line fitting at the pipe. The brace member and whatever fastens the other end to the building structure are separate items and have to be ordered alongside it. Budget the full brace assembly, not just this piece, when you are pricing out a bracing point.

It weighs 6.4 lb, so it's a one-hand piece off the ladder. Nothing about installing it needs lifting equipment, which matters when you are setting several braces on a long main and working off a lift.
