The Simpson RTC44 Rigid Tie Corner Connector is a 14-gauge steel post-to-joist connector designed to secure two horizontal wood members to a vertical 4x4 post at a precise 90 deg. angle. Built by Simpson with a Zinc Galvanized, G90 finish for dependable corrosion resistance, this rigid tie corner delivers a strong, reliable connection for structural framing, deck construction, and a wide range of utility carpentry projects where square, locked corners are essential.

Key Features

• 90 deg. rigid corner connection - locks two wood members to a vertical post at an exact right angle, eliminating the play and weakness associated with angled fastening alone
• 14-gauge steel construction - provides heavy-duty strength suited for load-bearing framing and structural utility applications
• Zinc Galvanized, G90 finish - adds a protective corrosion-resistant coating that holds up in demanding outdoor and exposed framing environments
• Designed for 4x4 post and 4x joist members - fits standard lumber dimensions so the connector drops into place without cutting, shimming, or modification
• Compatible with 16d sinkers or SD10 fasteners - works with widely available nail and screw options, keeping installation straightforward on the job site

Why This Product

• Purpose-built corner geometry - the rigid tie design is specifically engineered to form a 90 deg. post-to-joist connection, giving builders a dedicated connector rather than relying on improvised fastening methods that can compromise joint integrity
• Lasting outdoor performance - the G90 galvanized coating resists corrosion at a level suited for exposed structural applications, helping the connector maintain its holding power over time in tough conditions
• Versatile across framing projects - from deck framing to utility structures, the RTC44 functions as a practical, multi-application connector that secures wood members in a variety of 90 deg. corner configurations
• Made in the United States to Simpson quality standards - the connector is manufactured domestically under the same engineering standards that make Simpson a trusted name in structural connectors
