B-LINE SB307BYZ – Frequently Asked Questions
1) What size bolt does the B-Line SB307BYZ diagonal brace take?
The SB307BYZ auxiliary support brace is punched with 11/16 inch diameter holes, so it takes 5/8 inch hardware with normal clearance. The bolts, nuts and channel spring nuts are not part of the brace itself, so order the fasteners you need alongside it.
2) How big is the B-Line SB307BYZ support brace, and will it fit in a tight ceiling space?
Dimensions are 5.75 by 3.5 by 1.75 inches, at 2.1 lb. That is a compact single diagonal brace, not a long kicker, so it suits short-throw bracing off a strut run or a bracket where you don't have room to swing a full-length diagonal strut. Measure your available clear space against those three numbers before committing.
3) Will the B-Line SB307BYZ brace bolt to standard 1-5/8 inch strut channel?
The brace is 1.75 inches wide with 11/16 inch holes, which is the standard punching a 5/8 inch channel bolt and spring nut drop into. Anything with a slot or hole at 11/16 inch will take it. What you need to confirm on your own run is the hole spacing on the mating member, since the brace has to land on two existing holes to triangulate the joint.
4) Is the yellow zinc finish on this B-Line brace okay for outdoor or damp locations?
The SB307BYZ is steel with a yellow zinc chromate finish. That is an indoor, dry-to-occasionally-damp coating: it handles mechanical rooms, ceiling plenums and interior racks well. For exterior runs, wash-down areas, or anywhere the steel sees standing water or salt, step up to a hot dip galvanized or stainless brace instead.
5) What is a single diagonal brace used for in a strut or conduit support system?
A single diagonal brace ties a horizontal strut member back to a vertical one at an angle, turning a two-piece L joint into a triangle. That triangle is what stops the arm from sagging or racking under load, which matters on cantilevered conduit racks, trapeze hangers and equipment stands. "Single" means one brace per joint, on one face, as the B-Line SB307BYZ is built; a doubled or knee-brace arrangement is used where the connection sees load from both directions.
6) Does the B-Line SB307BYZ brace carry a UL listing or seismic certification?
The SB307BYZ is supplied as a plain steel fitting with no certification attached to it. If you are bracing to a seismic or a specific structural spec, the engineer of record specifies the assembly and the fastener capacity, and that is the document your inspector reads. Use this brace where the drawing calls for a general purpose single diagonal, not where a listed seismic component is named.
7) How do I order the right B-Line brace, and what is the part number?
Order it as B-Line SB307BYZ. That single part number covers the steel single diagonal brace in yellow zinc with 11/16 inch holes; there are no finish or size options to pick between on it. Braces are ordered by the each, so count one per joint you intend to triangulate.
