The Simpson MFCB45.5-R25 5-1/2 in. Bypass Framing Fixed-Clip Connector by Simpson Strong-Tie is a medium-duty fixed-clip connector engineered for cold-formed steel (CFS) curtain wall framing and a wide range of steel-to-steel bypass framing applications. Built from 14-gauge (68 mil) steel and finished with a G90 zinc galvanized coating, this connector delivers multi-directional load capacity and design flexibility backed by more than 50 years of Simpson Strong-Tie product design, testing, and manufacturing experience. This listing includes 25 connectors.

Key Features

• Rated for tension, compression, shear, and in-plane loads - handles the full spectrum of structural framing demands in a single connector, reducing the need to source multiple hardware types
• Varying screw and anchorage patterns achieve different load levels - gives engineers and designers the flexibility to dial in the exact load performance required for each project without switching products
• Strategically placed stiffeners, embossments, and anchor holes - maximize connector performance and structural efficiency, helping to maintain integrity under demanding CFS framing conditions
• 14-gauge (68 mil) steel construction - provides higher capacity than lighter-gauge alternatives, making this connector well-suited for curtain wall framing and other heavy-demand structural applications
• G90 zinc galvanized finish - delivers extra corrosion resistance for long-term durability in framing environments where moisture exposure is a concern
• Installs with #12 self-drilling screws to CFS framing - compatible with standard cold-formed steel fastening methods for a straightforward, field-proven installation process

Why This Product

• Multi-load rating in one connector - because the MFCB45.5-R25 is rated for tension, compression, shear, and in-plane loads, designers can use a single connector type across multiple framing conditions rather than specifying separate hardware for each load direction
• Built for design flexibility - the ability to vary screw and anchorage patterns to conform to desired load levels means this connector adapts to project-specific engineering requirements without requiring custom fabrication
• Performance-optimized geometry - strategically placed stiffeners, embossments, and anchor holes are engineered features - not afterthoughts - that translate directly into maximized connector performance in real-world CFS framing installations
• Backed by 50-plus years of structural connector expertise - Simpson Strong-Tie developed this connector as part of a comprehensive approach to cold-formed steel construction, meaning the design has been rigorously tested to meet the demands of curtain wall framing, lateral solutions, and steel-to-steel bypass framing connections
