The Simpson MSJC10.25-R15 CFS Steel-Joist Connector is a 12-gauge (97 mil) G90 zinc galvanized clip engineered specifically for cold-formed steel joist, rafter, and underside-of-metal-deck applications. Its unique clip dimensions enable 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 eliminate predrilling and readily accommodate 6 in., 8 in., 10 in., and 12 in. on-center metal-deck flutes. This connector is made in the United States and sold in a 15-count pack.

Key Features

• Prepunched 3/8 in. holes - eliminate the need for predrilling, reducing labor time and installation cost on the job site.
• Intuitive fastener hole positions - ensure accurate clip placement in accordance with design intent and support a wide range of application requirements, giving installers built-in flexibility.
• Hard-side or soft-side attachment compatibility - angle lengths accommodate either orientation for joists with return lips up to 3/4 in., making this connector versatile across CFS framing configurations.
• 4-1/2 in. leg length - enables soft-side connections for joists with flanges up to 3-1/2 in., covering a broad range of common CFS joist profiles.
• Kicker-to-metal-deck application support - extends the utility of a single connector type across multiple structural connection scenarios, simplifying procurement.
• 12-gauge (97 mil) steel construction - delivers the structural strength required for demanding CFS framing and metal-deck applications.
• G90 zinc galvanized finish - provides extra corrosion resistance, helping the connector hold up in moisture-exposed or demanding construction environments.

Why This Product

• Designed specifically for CFS framing - unlike generic angle clips, this connector's dimensions and hole patterns are purpose-built for cold-formed steel joist, rafter, and metal-deck applications, so it fits correctly and performs as designed without field modification.
• Installation flexibility built into every clip - the ability to switch between hard-side and soft-side attachment, combined with intuitive hole placement, means fewer errors on the job site and more confidence that the connection meets design requirements.
• Prepunched holes eliminate a common time-consuming step - by removing the need to predrill on site, installers can move faster through repetitive connections, translating directly to lower labor costs per completed connection.
• Multi-application capability in one product - from open-side joist connections to underside-of-metal-deck and kicker-to-metal-deck applications, a single connector handles several common CFS scenarios, reducing the number of different fasteners and clips a crew needs to manage.
