The Simpson SJC 2 in. x 4-1/2 in. x 8-1/4 in. 14-Gauge Galvanized Steel-Joist Connector by Simpson Strong-Tie is engineered specifically for cold-formed steel (CFS) joist, rafter, and underside of metal-deck applications. The unique clip dimensions enable easy installation on the open side of joists and rafters with up to 3-1/2 in. flanges and return lips up to 3/4 in. For metal-deck applications, the prepunched 3/8-in. holes easily accommodate 6-in., 8-in., 10-in., and 12-in. on-center metal-deck flutes. This package includes 15 connectors.

Key Features

• Prepunched holes eliminate predrilling - reduces labor time and installation cost on the jobsite, letting crews work faster without sacrificing accuracy.
• Intuitive fastener hole positions - guide accurate clip placement in accordance with design intent, supporting a wide range of design and application requirements while providing installation flexibility.
• Angle lengths accommodate hard-side or soft-side attachment - gives installers the versatility to work with joists and rafters that have return lips up to 3/4 in., reducing the need for custom solutions.
• 4-1/2 in. leg length enables soft-side connections - specifically supports joists with flanges up to 3-1/2 in., expanding the range of compatible CFS framing profiles.
• Compatible with kicker-to-metal-deck applications - extends the connector's usefulness beyond standard joist and rafter connections for greater jobsite versatility.
• Made from 14-gauge (68 mil) steel - provides the structural integrity demanded by CFS framing applications where connector strength is critical.
• G90 zinc galvanized coating - delivers extra corrosion resistance to help the connector hold up in demanding or moisture-prone environments.

Why This Product

• Purpose-built for CFS framing - the SJC connector is specifically designed for cold-formed steel joist, rafter, and metal-deck applications, meaning the geometry and hole patterns are optimized for the exact conditions installers encounter rather than adapted from a general-purpose clip.
• One connector, multiple applications - from open-side joist and rafter connections to kicker-to-metal-deck applications, the SJC8.25 handles a broad range of CFS framing scenarios, helping contractors simplify their material inventory on multi-application projects.
• Faster installation without compromising accuracy - prepunched 3/8-in. holes and intuitive fastener positions work together to eliminate predrilling and reduce guesswork, cutting installation time while supporting code-compliant placement.
• Durable construction for long-term performance - the combination of 14-gauge steel and a G90 galvanized finish means these connectors are built to resist both structural and environmental demands typical of CFS construction environments.
