The Simpson SS4.5 Triple 2x Stud Shoe is a 16-gauge galvanized connector engineered by Simpson to reinforce vertical wall studs that have been drilled or notched during construction. Sized for a triple nominal 2x stud, this stud shoe is the go-to solution when a large hole has been bored through framing to accommodate a plumbing waste line. It installs directly over the outside diameter of the pipe and functions as part of a total member replacement in structural applications, restoring tension load resistance to wall framing where stud integrity has been compromised.

Key Features

• Installs over pipe up to 2-3/8 in. outside diameter - fits around typical plumbing waste lines without requiring removal or rerouting of the pipe, saving time on the job site.
• Code listed for both building and plumbing codes - gives contractors and inspectors confidence that the repair meets compliance requirements in residential and commercial framing applications.
• Reinforces studs that have been drilled or notched - restores structural integrity to compromised wall framing members, reducing the risk of long-term wall movement or failure.
• Designed to resist tension loads only - purpose-built load resistance means the connector is optimized for the specific forces acting on a drilled or notched stud in a vertical wall assembly.
• Sized for a triple nominal 2x stud - the wider profile provides full coverage across a three-stud assembly, making it well suited for load-bearing and plumbing-adjacent wall configurations.
• Made from 16-gauge steel - heavy-gauge construction delivers the strength and rigidity needed for structural stud reinforcement applications.
• G90 zinc galvanized finish - provides corrosion resistance that helps the connector hold up in moisture-prone environments where plumbing penetrations are common.

Why This Product

• A purpose-built fix for a common framing problem - when plumbers bore through wall studs for waste lines, the stud's structural capacity is reduced. The SS4.5 is specifically designed to address this scenario, providing a code-recognized path to restore wall framing performance.
• Dual code listing simplifies the approval process - because the SS4.5 is listed under both building and plumbing codes, it bridges the gap between two trades and reduces back-and-forth with inspectors on mixed-discipline projects.
• Corrosion-resistant coating suits wet-area installations - the G90 galvanized finish is well matched to the damp conditions that often surround plumbing penetrations, helping the connector maintain its structural function over time.
• Straightforward installation with standard fasteners - the connector installs using common nails, keeping the repair process practical and accessible for framing and finish crews without specialized tools or hardware.

Frequently Asked Questions

What type of loads is the Simpson SS4.5 stud shoe designed to resist?

The SS4.5 is designed to resist tension loads only. It is not intended for compression load applications and should be used accordingly within structural wall framing.

What is the maximum pipe outside diameter that the SS4.5 can install over?

The SS4.5 installs over pipe up to 2-3/8 in. outside diameter, making it well suited for reinforcing studs drilled to accommodate typical plumbing waste lines.

Is the Simpson SS4.5 approved under building and plumbing codes?

Yes. The SS4.5 is code listed for both building and plumbing codes, providing confidence in compliance for residential and commercial construction projects where notched or drilled studs require reinforcement.

How many studs does the SS4.5 accommodate, and what fasteners are required for installation?

The SS4.5 is sized for a triple nominal 2x stud. Installation requires (14) 0.148 in. x 3 in. nails for a proper, code-compliant connection.
