The Simpson LTP5 4-1/2 in. x 5-1/8 in. Galvanized Lateral Tie Plate is an engineered framing anchor from Simpson that is designed to transfer shear forces at plate-to-rim board or blocking connections. Spanning the subfloor at the top of the blocking or rim joist, this lateral tie plate delivers the structural reliability that engineers and contractors depend on for both residential and commercial framing. Embossments built into the plate enhance performance and allow for design flexibility, while the G90 galvanized steel construction stands up to demanding jobsite conditions.

Key Features

• Spans subfloor at the top of the blocking or rim joist - positions the connector precisely where shear transfer is needed, creating a dependable connection between the top plate and the rim board or blocking.
• Nail holes spaced to prevent wood splitting - supports both single and double top plate applications without compromising the integrity of the framing lumber.
• May be installed over plywood sheathing - adds flexibility to the installation so the plate can be applied directly to sheathed assemblies without requiring additional prep work.
• Embossments enhance performance - the formed embossments increase the connector's structural capacity while maintaining design flexibility across common framing configurations.
• Made from 20-gauge steel - provides a strong, consistent base material engineered and tested to meet the demands of structural framing applications.
• G90 zinc galvanized coating - delivers extra corrosion resistance, helping the connector hold up in moisture-prone framing environments over the long term.
• Install with 8d x 1 1/2 in. nails - a straightforward fastener requirement that keeps installation simple and consistent across the jobsite.

Why This Product

• Engineered for shear transfer where it counts - the LTP5 is specifically designed to anchor the top plate to the rim joist or blocking, addressing one of the most critical lateral load paths in a framed structure and giving builders a connector sized and shaped for the job.
• Installation flexibility built in - the ability to install over plywood sheathing combined with nail hole spacing that works for single and double top plates means the LTP5 adapts to real-world framing conditions rather than requiring ideal ones.
• Corrosion resistance for lasting performance - the G90 galvanized finish goes beyond basic protection, making this framing anchor a dependable choice in environments where moisture exposure is a concern.
• Backed by Simpson engineering and quality standards - Simpson connectors are engineered, tested, and manufactured to the highest quality standards, giving contractors and engineers confidence that the LTP5 will perform as specified on every project.

Frequently Asked Questions

Where is the Simpson LTP5 installed in a framing assembly?

The LTP5 spans the subfloor at the top of the blocking or rim joist, serving as a lateral tie plate that transfers shear forces between the plate and the rim board or blocking.

Can the LTP5 be installed over plywood sheathing?

Yes. The LTP5 may be installed over plywood sheathing, providing additional flexibility in how it is applied to framing assemblies.

What fasteners should be used to install the LTP5?

The LTP5 should be installed with 8d x 1-1/2 in. nails. The nail holes are specifically spaced to prevent wood splitting for both single and double top plate applications.

What corrosion protection does the LTP5 have?

The LTP5 is manufactured from 20-gauge steel with a G90 zinc galvanized coating, providing enhanced corrosion resistance suitable for demanding framing environments.
