The Simpson RBC Roof Boundary Clip is engineered to aid installation and transfer shear loads between the roof diaphragm and wall, making it a dependable choice for structural connections in both residential and commercial framing. Built-in locator tabs simplify proper positioning during installation, and the clip is compatible with wood or masonry walls across roof pitches from 0/12 to 12/12. Field-bendable to match the required angle, the RBC adapts to job-site conditions while maintaining the structural performance that demanding diaphragm-to-wall connections require.

Key Features

• Field bend to desired angle (one time only) - allows on-site adjustment to match the exact roof pitch without the need for additional hardware or pre-fabricated variants
• 20-gauge steel construction - provides the rigidity and load-handling capacity needed for reliable shear transfer at the roof-to-wall connection
• G90 zinc galvanized finish - delivers extra corrosion resistance, helping the clip hold up in moisture-exposed framing environments over the long term
• Built-in locator tabs - take the guesswork out of positioning, ensuring consistent and code-conforming placement on every installation
• Compatible with wood or masonry walls - gives builders flexibility to use a single clip type across different wall assemblies and construction methods
• Handles roof pitches from 0/12 to 12/12 - covers the full range from flat commercial roofs to steeply pitched residential applications with one versatile clip design

Why This Product

• Dual-substrate versatility - because the RBC works on both wood and masonry walls, contractors can stock a single clip model and deploy it confidently across a wide range of structural wall types and project scopes
• Pitch-range coverage from flat to steep - with compatibility spanning 0/12 to 12/12, this roof boundary clip eliminates the need to source different connectors for different roof geometries on the same job
• Faster, more accurate placement - the integrated locator tabs guide the installer to the correct position immediately, reducing layout time and the risk of misalignment during roof diaphragm attachment
• Built for lasting performance - the G90 galvanized coating on 20-gauge steel means the clip resists corrosion in real-world framing conditions, supporting the structural integrity of the shear connection well beyond initial installation
