B-LINE SB309BTG – Frequently Asked Questions

1) How long is the B-Line diagonal sway brace and will it fit my available ceiling space?
It measures 10.5 inches in length, 1.75 inches wide and .38 inch thick, so it needs roughly a foot of diagonal clearance between the rod and the structure above. In tight plenums measure the diagonal run before committing.
2) Does this brace come with nuts, washers or rod?
The SB309BTG is the steel brace only. You supply the 5/8-11 all-thread rod plus the nuts and washers to land it, since rod length depends on your drop height.
3) Is one single diagonal brace enough, or do I need a pair?
This is a single diagonal brace, meaning it resists movement in one plane only. Where sway has to be controlled in both directions along and across a runway, braces are installed in opposing pairs at the same rod point. Order quantity accordingly.
4) Is the Telco gray finish on this Eaton B-Line brace suitable for a telecom or data center room?
Telco gray powder coat over steel is the standard finish used to match cable runway and rack hardware in central office and data center rooms, so the brace blends with existing overhead ironwork rather than standing out as plain galvanized.
5) How much does the SB309BTG brace weigh for load calculations on my overhead support?
Each brace weighs 1.84 lb. That is the dead load you add per brace point when totaling an overhead runway or tray support, and it is light enough for one person to hold in place while starting the rod nuts.
6) Does the B-Line SB309BTG carry a UL listing or seismic certification?
The SB309BTG is supplied as a plain steel auxiliary support brace with no certification designation attached to it. If your job carries a seismic bracing submittal requirement, the bracing assembly has to be engineered and approved as a system by the designer of record.
