The Simpson RTC2Z Rigid Tie Corner Connector from Simpson is built for anyone who wants a rock-solid 90 deg. corner joint without the guesswork or weakness that comes with traditional fastening methods. Designed for workbenches, storage shelving units, and similar structural projects, this connector joins a 2x2, 2x3, or 2x4 vertical member to two 2x3 or greater horizontal members, forming a clean, precise corner that holds up over time. The ZMAX galvanized finish makes it equally at home in exterior settings or wherever treated lumber is in use.

Key Features

• No angled cuts or angled fastening - eliminates the risk of splitting wood during installation, keeping your materials and your project intact
• Stronger than other methods of corner construction - delivers a more secure joint than toe-nailing or traditional miter-based approaches, so finished structures are built to last
• Quickly and accurately align framing members - the rigid design locks members into position at a true 90 deg. corner, reducing layout time and the chance of assembly errors
• Made from 18-gauge steel - provides a durable, load-bearing connection that holds its shape under the demands of workbench and shelving use
• ZMAX galvanization offers extra corrosion resistance - makes this connector suitable for exterior applications and direct contact with treated wood, where moisture and chemical exposure can break down standard finishes
• Installs with SD8x1.25 Strong-Drive screws - a specified fastener requirement means no guessing about hardware, keeping the connection properly engineered from start to finish

Why This Product

• A smarter way to build corners - instead of relying on angled cuts or toe-nailing that can split lumber and weaken joints, this rigid tie connector delivers a stronger, cleaner corner connection that traditional framing methods simply cannot match
• Built for real-world exposure - the ZMAX galvanized coating is specifically suited for exterior construction and treated-wood applications, so the connector resists corrosion even in demanding environments
• Speeds up the build without sacrificing accuracy - the connector automatically aligns framing members at a precise 90 deg. corner, cutting down on layout time and helping both DIYers and professionals get consistent results faster
• Versatile fit across common lumber dimensions - compatibility with 2x2, 2x3, and 2x4 vertical members paired with 2x3 or greater horizontal members means this connector works across a wide range of workbench and shelving configurations without requiring special sizing
