The Simpson MSJC8.25-R15 CFS Steel-Joist Connector is a 12-gauge G90 galvanized clip engineered specifically for cold-formed steel framing, delivering reliable performance across CFS joist, rafter, and underside of metal-deck applications. The unique clip geometry enables easy installation on the open side of joists and rafters with flanges up to 3-1/2 in. and return lips up to 3/4 in., while prepunched 3/8 in. holes accommodate 6 in., 8 in., 10 in., and 12 in. on-center metal-deck flutes without any predrilling. Built to 97-mil thickness and finished with a G90 zinc galvanized coating, this connector is a practical, corrosion-resistant solution for structural steel framing professionals tackling a wide variety of light-gauge steel connections.

Key Features

• Prepunched 3/8 in. holes - eliminate the need for predrilling on the job site, reducing installation time and labor cost across metal-deck and joist applications.
• Intuitive fastener hole positioning - guides accurate clip placement in accordance with design intent, supporting a wide range of load and application requirements while giving installers flexibility in the field.
• Angle lengths sized for hard-side or soft-side attachment - accommodate either connection method for CFS joists with return lips up to 3/4 in., so one connector handles multiple framing scenarios.
• 4-1/2 in. leg length - enables reliable soft-side connections on joists with flanges up to 3-1/2 in., covering the full practical range of common CFS joist profiles.
• Compatible with kicker-to-metal-deck applications - expands the connector's usefulness beyond standard joist and rafter work to support specialized CFS framing configurations.
• 12-gauge (97 mil) steel construction - provides the structural thickness needed for demanding light-gauge steel framing applications without excess bulk.
• G90 zinc galvanized finish - delivers enhanced corrosion resistance, helping the connector maintain integrity in environments where moisture exposure is a concern.

Why This Product

• Versatility across multiple CFS applications - a single connector design handles CFS joist framing, rafter connections, underside of metal-deck installations, and kicker-to-metal-deck applications, reducing the number of different parts needed on a job site.
• Faster installation without predrilling - the prepunched hole pattern lets crews move quickly from one connection to the next, directly lowering installation labor costs on steel-framing projects.
• Engineered specifically for cold-formed steel framing - unlike generic angle clips, the unique clip dimensions and intuitive fastener hole positions are purpose-built for CFS joist and rafter geometry, including joists with flanges up to 3-1/2 in. and return lips up to 3/4 in., supporting accurate, design-compliant installations.
• Built-in corrosion protection for long-term performance - the G90 galvanized coating goes beyond basic zinc treatment to provide extra durability, making these clips a dependable choice for framing assemblies where lasting material integrity matters.
