B-LINE SB309AYZ – Frequently Asked Questions

1) What threaded rod size does the B-Line SB309AYZ support brace work with?
The SB309AYZ single diagonal brace is sized for 1/2-13 all-thread rod, and the mounting hole is 9/16 inch to clear that rod. If your hanger run is on 3/8-16 rod, this is not the brace for it.
2) Is the yellow zinc finish on this B-Line brace suitable for outdoor or wet locations?
The brace is steel with a yellow zinc chromate finish. That is a mild indoor corrosion coating, fine for dry interior mechanical and electrical spaces. For exterior, wash-down, or corrosive environments, specify hot dip galvanized or stainless support hardware instead.
3) What is a single diagonal brace used for on a threaded rod hanger?
A single diagonal brace ties one rod-hung support back at an angle to resist sway and lateral movement, rather than carrying gravity load like the rod itself. The SB309AYZ handles one diagonal per connection point, so runs needing bracing in two directions take two braces.
4) Does the B-Line auxiliary support brace come with nuts, washers or rod?
What you receive is the steel brace itself. The 1/2-13 all-thread rod, nuts and washers needed to land it are ordered separately, so plan on hardware at both ends of every brace.
5) How much does the B-Line SB309AYZ brace weigh?
Each brace weighs 1.84 lb, which matters when you are adding the dead load of dozens of them to a rod-hung trapeze run and calculating anchor loading.
