Sihnman 24" x 13.5" 12-Pitch Gable Plate — Powder-Coated Black, 3mm Structural Steel

The Sihnman 24.0" x 13.5" powder-coated 12 pitch gable plate is a heavy-duty 3mm steel connector that provides a decorative, corrosion-resistant base for 12-pitch gable and truss roof joints.

This compact yet robust steel plate is made for builders, remodelers, and homeowners who want a clean, finished connection at the peak of a 12-pitch gable or on pergola and truss projects. The black powder-coated finish offers weather resistance and a refined look while the predrilled clearance holes speed up installation. Designed for both functional support and visual appeal, the Sihnman plate can be used in metal or timber framing where a 12-pitch bracket is required.

How does this gable plate fit a 12-pitch roof?

The plate is shaped and drilled to align with the geometry of a 12-pitch truss joint so rafters and ridge pieces meet flush and fasteners align consistently. It acts as a neutral base for fastening and helps maintain the intended roof angle during assembly. Because it’s pre-drilled for #10 and 1/4" fasteners, you’ll spend less time measuring and more time bolting parts together.

• Pre-drilled clearance holes sized for #10 and 1/4" screws
• Profile designed specifically for 12-pitch rafter geometry
• Helps centralize connections for consistent roof alignment

What materials and finish are used, and why does that matter?

This bracket is stamped from 3mm structural steel for strength under load and longevity in outdoor conditions. An industrial powder-coat finish minimizes corrosion and keeps the plate looking tidy next to cedar, treated lumber, or painted steel. The combination of thickness and coating makes it suited to both decorative and structural roles where exposed connections need to look polished.

• 3mm heavy-duty structural steel for high stiffness
• Black industrial powder coat for rust resistance and neat appearance
• Suitable for outdoor exposure when installed with compatible fasteners

How easy is installation for pros and DIYers?

Installation is straightforward: position the plate at the gable junction, align the rafters, and fasten through the provided holes. The plate’s predrilled pattern removes guesswork and reduces on-site drilling. Whether you’re a contractor on a jobsite or a homeowner doing a pergola, you’ll appreciate the consistent hole placement and solid contact area.

• Pre-punched holes for quick alignment and fastening
• Flat footprint simplifies clamping and tacking into place
• Works with common #10 and 1/4" fasteners—no specialty hardware needed

What kinds of projects are best for this bracket?

Use it wherever a 12-pitch gable intersection or decorative truss connection is needed: roof gables, pergola peaks, gazebo frames, or any truss plate application calling for a 12-pitch connector. Its decorative black finish makes it a good choice where the plate will remain visible and contribute to the overall look. It’s also useful for hybrid metal/wood assemblies where a strong, clean junction is required.

• Residential gable roof junctions at 12 pitch
• Pergola or gazebo ridge connections with visible hardware
• Truss base fan or decorative truss plate applications

Who is this for: This Sihnman gable plate suits contractors, roof framers, and DIY builders who need a robust, predrilled connector for 12-pitch gable and truss work. Choose it if you want a durable steel plate with a neat, powder-coated finish for projects where appearance and structural fit matter. If your project requires different pitch geometry or stainless corrosion resistance, confirm compatibility before ordering.
