The Simpson Strong-Tie TA9ZKT TA 8-1/4 in. 12-Gauge ZMAX Galvanized Staircase Angle is a heavy-duty structural connector engineered for use in structurally sound staircase framing. Manufactured by Simpson Strong-Tie, this staircase angle eliminates complicated stringer notching that can weaken the stair stringers, delivering a stronger, more reliable framing solution. Its narrow profile also makes it ideal for heavy-duty 90 deg. connections wherever a slimmer angle is required.

Frequently Asked Questions

What is the purpose of the Simpson TA9ZKT staircase angle?

The TA9ZKT staircase angle is designed for use in structurally sound staircase framing. It eliminates complicated stringer notching that can weaken the stair stringers, providing a stronger and more consistent framing connection.

What type of coating does the TA9ZKT have, and why does it matter?

The TA9ZKT features ZMAX galvanization, which offers extra corrosion resistance compared to standard galvanized coatings. This makes it especially well-suited for exterior applications and use with treated wood, where exposure to moisture and chemicals is a concern.

What fasteners are used to install the Simpson TA9ZKT?

The TA9ZKT is installed with 1/4 in. x 1-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws, which are included with the kit.

Can the TA9ZKT be used for applications other than stair framing?

Yes. In addition to staircase framing, the TA9ZKT is also ideal for heavy-duty 90 deg. connections where a narrow angle is needed, making it a versatile connector for various structural framing projects.
