The Simpson RSP4 4-1/2 in. Reversible Stud-Plate Tie by Simpson is engineered to create a continuous load path that resists uplift in wood-framed wall assemblies. Its reversible design lets a single connector join a wood stud to either a double top plate or a sill plate, while built-in locating tabs keep the tie correctly positioned during installation for consistent, accurate results. Constructed from 20-gauge steel with a G90 zinc galvanized finish, this stud-plate connector is built to perform in demanding residential and light commercial framing applications where wind and seismic resistance are required.

Key Features

• Reversible design - one connector works at the top plate or sill plate, reducing the need for multiple bracket types on the job site
• Embossments that strengthen the stud-plate connection - adds rigidity at the connection point, improving load transfer between the stud and plate
• Designed to resist wind and seismic forces - helps meet code requirements in high-wind and seismic zones, giving builders and inspectors greater confidence
• Locating tabs for proper placement - guide the tie into the correct position during installation, reducing the chance of misalignment and rework
• 20-gauge steel construction - provides reliable structural strength while keeping the connector lightweight and easy to handle on the framing wall
• G90 zinc galvanized coating - delivers extra corrosion resistance to help the connector maintain its structural integrity in moisture-prone environments

Why This Product

• One connector, two applications - the reversible stud-plate tie eliminates the need to stock separate connectors for top-plate and sill-plate connections, simplifying material management on framing projects
• Built for code-required load paths - specifically designed to create a continuous load path resisting uplift, making it a practical choice for wood-framed walls in wind- and seismic-rated construction
• Installation accuracy built in - the locating tabs help position the tie correctly against the plate before fastening, which speeds up the process and supports consistent, code-compliant results across multiple connections
• Durable finish for real-world conditions - the G90 galvanized coating offers a higher level of corrosion protection than standard galvanizing, making the RSP4 a dependable option for framing applications where long-term performance matters

Frequently Asked Questions

What does "reversible" mean for the RSP4 stud-plate tie?

The reversible design means the RSP4 can be oriented in either direction, allowing it to connect a wood stud to either a double top plate or a sill plate of a wood-framed wall without requiring a separate connector for each application.

What fasteners should be used to install the RSP4?

The RSP4 should be installed with 8d x 1-1/2 in. nails or #9 x 1-1/2 in. Strong-Drive SD screws for proper performance.

What is the purpose of the locating tabs on the RSP4?

The locating tabs are designed to aid in attaching the tie to the plates, ensuring proper placement during installation for consistent and accurate positioning.

What protection does the G90 galvanized coating provide?

The G90 zinc galvanized coating provides extra corrosion resistance, helping the RSP4 maintain its structural integrity in environments where moisture exposure is a concern.
