The Simpson MSSC6.25KW-KT20 Kneewall Connector is a rigid cold-formed steel (CFS) connector from Simpson engineered for moment-resisting kneewall lighter-duty applications in steel framing construction. Designed to work in tandem with BP 1/2-3 bearing plates - which are included in each package - this 6-1/4 in. connector delivers the increased load capacity required for steel framing applications, making it a dependable choice for supporting load-bearing walls in curtain-wall construction, drywall, and kneewall projects.

Key Features

• One simple custom hole pattern for each stud size - simplifies specification and installation, reducing layout time and the chance of field errors.
• 3/8 in. diameter anchor bolt location - enables easy tool access during fastening, helping installers work efficiently even in tight framing conditions.
• BP 1/2-3 bearing plates included - each package contains both connectors and matching bearing plates so the complete kneewall connection solution arrives together, ready to install.
• MSSC connector made from 97 mil (12 ga.) steel rated at 50 ksi - delivers the structural rigidity and load capacity demanded by cold-formed steel construction applications.
• Compatible with 8 in. deep steel framing members - the 6-1/4 in. connector is sized precisely for this member depth, ensuring a proper fit without field modification.
• Zinc galvanized (G90) finish on the MSSC connector - provides corrosion resistance suited to demanding construction environments, helping the connection maintain long-term integrity.

Why This Product

• A complete, coordinated connection kit - the MSSC connectors and BP 1/2-3 bearing plates are packaged together and engineered to work as a system, giving contractors everything needed for moment-resisting kneewall connections without sourcing components separately.
• Designed specifically for cold-formed steel framing - unlike generic connectors, the MSSC series is purpose-built for CFS construction, delivering the increased load capacity that steel applications require across curtain-wall, kneewall, and drywall projects.
• Simplified installation through consistent hole patterns - a single custom hole pattern per stud size means faster, more predictable installation in the field, reducing labor time and specification complexity on the job site.
• Heavy-gauge construction for reliable structural performance - with the MSSC made from 12 ga. steel and the BP bearing plate from 3 ga. steel, this connector kit is built to handle the structural demands of load-bearing wall support applications in commercial and residential steel framing.
