Product Description
The Simpson Structural Spacer Bracer is an 18-gauge (43 mil), G90 galvanized cold-formed steel bracing component engineered specifically for structural exterior cold-formed steel stud walls. Designed to reduce the installed cost of CFS framing, it enables faster stud layout while minimizing the need for bridging clips with on-module studs. The SBR provides continuous bracing along the full length of the stud and accommodates head-of-wall slip conditions, making it a reliable choice for light-gauge steel framing assemblies. Critically, it is backed by bracing load data derived from assembly testing, giving structural designers verified performance data to mitigate risk and maximize confidence in design specifications.
Key Features
- Patent-pending precision-engineered prepunched slots support 12 in., 16 in., and 24 in. on-center stud spacing - eliminates the need to mark the top track for layout, accelerating stud placement and reducing labor time on the job site.
- Accommodates 3-5/8 in. and 6 in. studs in thicknesses from 33 mil (20 ga.) through 68 mil (14 ga.) - broad compatibility across common cold-formed steel framing dimensions reduces the need to stock multiple bracing products.
- Hat-section profiles enable clip attachments using Simpson LSSC or RCA connectors in off-layout or end-of-run conditions - maintains structural continuity even where standard on-module spacing cannot be achieved.
- Prepunched holes allow rapid screw installation at spacer-bracer splices - speeds up connections at axial load-bearing stud locations without additional field drilling or layout work.
- G90 zinc galvanized finish - delivers extra corrosion resistance suited to exterior structural wall applications where long-term durability is required.
- Made from 18-gauge (43 mil) cold-formed steel - provides the structural rigidity needed for load-bearing exterior wall assemblies while keeping the component lightweight for efficient handling.
Why This Product
- Reduces installed cost in CFS framing projects - the prepunched slot design spaces studs automatically at 12 in., 16 in., or 24 in. on-center without manual track marking, and minimizes the use of bridging clips, cutting both material and labor costs on structural exterior walls.
- Assembly-tested bracing load data backs every installation - unlike products relying solely on calculated values, the SBR comes with performance data from actual assembly testing, giving designers and specifiers verified figures that reduce project risk.
- Built specifically for structural exterior cold-formed steel stud walls - while similar products address interior applications, the SBR is purpose-engineered for the higher demands of exterior structural walls, including head-of-wall slip conditions, so the right tool is matched to the right application.
- Flexible connector options handle non-standard conditions - the hat-section profile works with Simpson LSSC or RCA connectors at off-layout and end-of-run locations, so framers are not left without a code-compliant solution when field conditions deviate from the plan.

Frequently Asked Questions
- What stud sizes and thicknesses is the SBR/43-R680 compatible with?
- The SBR accommodates 3-5/8 in. and 6 in. studs in thicknesses ranging from 33 mil (20 ga.) through 68 mil (14 ga.), making it suitable for a wide range of cold-formed steel framing applications.
- How does the SBR differ from the DBR spacer bracer?
- The SBR is designed specifically for structural exterior walls, while the DBR is intended for interior walls to eliminate stud bow and allow for quicker drywall attachment. Both products provide bracing along the length of the stud and accommodate head-of-wall slip conditions, but their intended structural applications differ.
- What on-center stud spacing options do the prepunched slots support?
- The patent-pending precision-engineered prepunched slots are strategically located to enable 12 in., 16 in., and 24 in. on-center stud spacing. These slots can also be used to space studs without having to mark the top track for layout, speeding up installation.
- What connectors are used when clip attachment is needed in off-layout or end-of-run conditions?
- In off-layout or end-of-run conditions, the hat-section profile of the SBR enables clip attachments to the stud using Simpson Strong-Tie LSSC or RCA connectors.
