The Simpson RTT22Z RTT 18-Gauge ZMAX Galvanized Rigid Tie Connector is an engineered wood framing connector from Simpson built to strengthen T-shaped outer corner connections where a horizontal 2x joist meets a vertical 2x post at a 90 deg. angle. Manufactured to the highest quality standards and trusted by engineers and contractors alike, this rigid tie connector is a reliable solution for residential framing, exterior structures, and code-compliant construction involving treated wood.

Key Features

• Strengthens T-shaped outer corner connections at 90 deg. angles - provides a secure, rigid joint where two members meet, reducing the risk of racking or movement in framed structures
• Compatible with 2x posts and 2x joists - sized specifically for standard dimensional lumber, making it a straightforward fit for common framing applications without modification
• Install vertical members first, then attach horizontal members - following this sequence simplifies alignment during installation and saves time on the job
• Made from 18-gauge steel - delivers a strong, durable connector profile that holds up under the structural demands of post-and-joist connections
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - goes beyond standard coatings to protect against the accelerated corrosion that treated lumber chemicals and outdoor moisture can cause

Why This Product

• Built for the conditions where standard connectors fall short - the ZMAX coating is specifically engineered to resist corrosion in exterior environments and when in contact with treated wood, giving this connector a longer service life in demanding conditions
• A trusted choice for both DIYers and professionals - Simpson rigid tie connectors are engineered and tested to perform, and are the go-to option for engineers and contractors working on projects that must meet building code requirements
• Designed for a precise, utility-ready fit - the RTT22Z connects 2x posts and 2x joists at a clean 90 deg. angle, making it a practical connector for a wide variety of wood framing configurations without the need for custom fabrication
• Installation-friendly design reduces guesswork on site - the recommended installation sequence (vertical members first, then horizontal) keeps alignment predictable, helping builders work efficiently even in tight framing layouts

Frequently Asked Questions

What type of connection is the RTT22Z designed for?

The RTT22Z is designed to strengthen T-shaped outer corner connections where two 1x members join another member at a 90 deg. angle, specifically connecting a 2x joist horizontally to a 2x post vertically.

What fasteners are required to install the RTT22Z?

The RTT22Z should be installed with SD8x1.25 or #9 x 1-1/2 in. Strong-Drive SD screws. Fasteners are not included with the connector.

Is the RTT22Z suitable for exterior or treated-wood applications?

Yes. The RTT22Z features ZMAX galvanization, which offers extra corrosion resistance specifically suited for exterior and treated-wood applications where standard coatings may not provide adequate protection.

What is the recommended installation sequence for the RTT22Z?

For easiest alignment, install vertical members first, then attach horizontal members when using the RTT22Z rigid tie connector.
