B-LINE SB308BYZ – Frequently Asked Questions
1) What size hole does the B-Line SB308BYZ double diagonal brace have, and what bolt does that take?
The SB308BYZ brace is punched with 11/16 inch holes, which is the standard strut-channel hole size for 1/2 inch bolts and channel nuts. That means it bolts up to 1-5/8 inch strut using the same 1/2 inch hardware you already stock for the run, so no drilling in the field.
2) Is a yellow zinc chromate brace suitable for outdoor or wet locations?
No. Yellow zinc chromate is an indoor, dry-location plating for the SB308BYZ brace. For rooftops, parking structures, wash-down areas or anything exposed to weather, specify a hot-dip galvanized or stainless brace instead. Putting yellow zinc outside is the most common way these end up rusting within a season.
3) What is a double diagonal brace used for on a strut trapeze?
A double diagonal brace ties a strut trapeze or rack back to the structure at an angle so the assembly resists sway and racking rather than relying on the vertical rods alone. The double form gives you two bolted legs off one piece, which is what you want where a single kicker would leave the frame free to rack in one direction. The SB308BYZ is the steel, 20 inch version of that part.
4) Does the B-Line SB308BYZ brace come with the bolts and channel nuts?
Plan on ordering fasteners separately. The SB308BYZ is supplied as the steel brace only, punched with 11/16 inch holes, so you will need 1/2 inch bolts with channel nuts or spring nuts at each strut connection plus whatever anchor suits the structural attachment.
5) What part number do I order for the yellow zinc double diagonal brace?
Order B-Line part SB308BYZ. The BYZ suffix is the yellow zinc chromate version; the same brace geometry is offered in other finishes under different suffixes, so confirm the suffix matches the environment you are installing in.
6) Does this B-Line brace carry a UL listing or seismic certification I can put on a submittal?
No certification is carried on the SB308BYZ brace, so do not show it as a listed or certified component on a submittal. If your drawing calls for a seismic-rated bracing assembly, the rating comes from the engineered bracing system and its calculations, not from this individual formed steel brace.
7) How much does one of these braces weigh for load and handling calculations?
Each SB308BYZ brace weighs 3.5 pounds. It is formed steel, so a bundle of them adds up fast on a multi-run job, but a single brace is a one-hand install off a ladder.
