The Simpson TA10SS 10-1/4 in. 12-Gauge Stainless-Steel Staircase Angle from Simpson Strong-Tie is purpose-built for structurally sound staircase framing, giving builders and contractors a reliable metal connector that strengthens stair-to-stringer joints without the drawbacks of traditional notching methods. Fabricated from 12-gauge stainless steel, this heavy-duty framing angle delivers the corrosion resistance needed for exterior builds and treated-wood assemblies, while its narrow profile makes it equally well suited for tight 90 deg. structural connections beyond staircase work.

Key Features

• Designed for structurally sound staircase framing - provides a secure, code-conscious connection between stair treads and stringers, giving builders confidence in the structural integrity of every step.
• Eliminates complicated stringer notching - removes the need for the notching process that can weaken stair stringers, preserving the full strength of the framing member and reducing labor time on the job.
• Ideal for heavy-duty 90 deg. connections where a narrow angle is needed - the compact profile fits into tight framing situations where standard wider angles will not, expanding the range of structural applications this connector can handle.
• Made from 12-gauge stainless steel - the heavy gauge delivers load-bearing rigidity, while stainless construction resists the corrosion and chemical exposure common in exterior environments and treated-lumber applications.
• Install with 1/4 in. x 1-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws - pairing this angle with the correct fastener ensures a proper, secure connection and maintains the structural performance the connector is rated for.

Why This Product

• Preserves stringer strength where it matters most - by eliminating the need for complicated notching, this staircase angle keeps stair stringers structurally intact, reducing the risk of long-term framing weakness caused by material removal.
• Stainless steel construction extends service life in demanding conditions - the corrosion-resistant finish holds up against moisture, weather, and the chemicals present in treated wood, making it a dependable choice for outdoor decks, porches, and other exterior stair applications.
• Versatile enough for staircase framing and general heavy-duty connections - its narrow profile and 12-gauge strength mean this angle works well beyond staircase use, serving as a practical solution for any heavy-duty 90 deg. framing connection where space is limited.
• Domestic manufacturing and a trusted brand - engineered and produced by Simpson Strong-Tie, a name closely associated with structural connectors, this angle is built to consistent quality standards that professionals rely on across residential and commercial framing projects.

Frequently Asked Questions

What fasteners should be used to install the TA10SS staircase angle?

Install with 1/4 in. x 1-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws for a proper and secure connection.

Why is the TA10SS made from stainless steel?

Stainless steel offers extra corrosion resistance, making the TA10SS well suited for exterior and treated-wood applications where standard steel hardware may be prone to deterioration over time.

Does the TA10SS eliminate the need for stringer notching?

Yes. The TA10SS is specifically designed to eliminate complicated stringer notching, which can weaken stair stringers, while still providing a structurally sound staircase framing connection.

Can the TA10SS be used for applications other than staircases?

Yes. In addition to staircase framing, the TA10SS is also ideal for heavy-duty 90 deg. connections where a narrow angle is needed.
