The Simpson RTC22Z RTC 18-Gauge ZMAX Galvanized Rigid Tie Corner for 2x is a uniquely engineered corner connector from Simpson Strong-Tie, designed to form a strong, rigid 90 deg. connection between two nominal 2x horizontal members and a nominal 2x vertical post. Ideal for the construction of workbenches and storage shelving units, this connector delivers superior strength and durability compared to traditional corner-building methods, while the ZMAX galvanized coating provides enhanced corrosion resistance for exterior and treated-wood applications.

Frequently Asked Questions

What size lumber is the RTC22Z designed to work with?

The RTC22Z is designed for use with nominal 2x members. It connects two nominal 2x2 horizontal members to a nominal 2x2 vertical post, forming a 90 deg. corner.

What fasteners are required to install the RTC22Z?

The RTC22Z should be installed with #9 x 1-1/2 in. Strong-Drive SD screws.

Why is the ZMAX finish important for this connector?

The ZMAX galvanization provides extra corrosion resistance, making the RTC22Z suitable for exterior applications and projects involving treated wood, where standard finishes may be insufficient.

Is the RTC22Z stronger than traditional corner construction methods?

Yes. The RTC22Z is stronger than other methods of corner construction and eliminates the need for angled cuts or angled fastening, which can split the wood and weaken the joint.
