The Simpson LTP4 3 in. x 4-1/4 in. Galvanized Lateral Tie Plate is an engineered structural connector from Simpson Strong-Tie designed to transfer shear forces for top plate-to-rim board or blocking connections. Built to the highest quality standards and trusted by engineers and contractors on projects ranging from residential framing to code-compliant structures, this lateral tie plate delivers a stronger, safer, and more efficient connection wherever wall framing meets rim board or blocking.

Key Features

• Nail holes spaced to prevent wood splitting - supports both single and double top plate applications without compromising the integrity of the surrounding lumber
• May be installed over plywood sheathing - gives framers flexibility across a wider range of wall assembly configurations without requiring special prep work
• 20-gauge steel construction - provides reliable structural strength in a connector sized for practical, everyday framing use
• Zinc Galvanized G90 coating - delivers extra corrosion resistance, extending the service life of the connector in demanding or moisture-prone environments
• Compatible with 8d x 1-1/2 in. nails or #9 x 1-1/2 in. Strong-Drive SD screws - works with common fastener options so installation fits naturally into standard framing workflows

Why This Product

• Purpose-built for shear force transfer - the LTP4 is specifically engineered to handle the lateral loads at top plate-to-rim board and top plate-to-blocking connections, making it a reliable choice when structural performance is a requirement, not an afterthought
• Designed to protect the wood around it - strategically spaced nail holes reduce the risk of splitting in single and double top plate framing, helping maintain the strength of the overall assembly, not just the connector itself
• Versatile across common framing scenarios - from installations directly over plywood sheathing to single and double top plate configurations, this connector adapts to a variety of wall assembly conditions without requiring additional hardware
• Corrosion-resistant finish for long-term durability - the G90 galvanized coating goes beyond basic protection, helping the connector hold up over time in environments where moisture exposure is a real concern
