The Simpson HCP2 HCP 18-Gauge Galvanized Hip Corner Plate for 2x is an engineered roof framing connector from Simpson built specifically for hip roof construction. It connects a rafter or joist to double top plates at a 45 deg. angle, delivering reliable resistance to both uplift and download forces at one of the most structurally demanding points on a roof. Engineered and tested to meet the highest quality standards, this hip corner plate is the trusted choice of contractors and engineers who need a connector that performs when it matters most.

Key Features

• Attaches HCP to double top plates - creates a secure, code-compliant connection at the hip rafter-to-plate joint without requiring custom fabrication.
• Birdsmouth not required for table uplift loads - simplifies rafter preparation and saves installation time, though a birdsmouth may still be required for download applications.
• Rafter may be sloped to 45 deg. - accommodates the angled geometry of hip roofs without additional hardware or cutting, making it purpose-built for this application.
• Made from 18-gauge steel - provides a strong, consistent base material that meets engineered load requirements for residential and light commercial framing.
• Zinc Galvanized G90 coating - delivers extra corrosion resistance, helping the connector hold up in environments where moisture exposure is a concern.

Why This Product

• Purpose-designed for hip roof framing - unlike general-purpose connectors, this plate is engineered specifically for the 45 deg. angle connections found at hip corners, reducing guesswork and improving structural integrity at a critical roof joint.
• Handles both uplift and download forces - the HCP2 is designed to resist forces in both directions, giving builders confidence that the connection performs under real-world loading conditions including wind uplift.
• Streamlined installation process - the straightforward attach-then-nail sequence works with standard framing nails and eliminates the need for a birdsmouth cut on uplift-load applications, keeping the job moving efficiently.
• Backed by Simpson engineering and testing - every connector in the Simpson lineup is engineered and tested to verified performance standards, making the HCP2 a dependable specification for projects that must meet building code requirements.
