The Simpson 2X Hip Corner Plate with ZMAX Finish is an 18-gauge steel connector engineered by Simpson to join a rafter or joist to double top plates at a precise 45 deg. angle, delivering a reliable hip corner connection for residential and light commercial wood framing projects.

Key Features

• 45 deg. angle connection to double top plates - purpose-built geometry ensures accurate hip corner alignment, removing guesswork from layout and reducing installation time.
• 18-gauge steel construction - provides solid structural integrity suited to the load demands of hip corner framing applications.
• ZMAX coating - delivers enhanced corrosion resistance beyond standard galvanized finishes, helping the connector hold up in moisture-prone or chemically treated lumber environments.
• Compatible with 2x member sizes - fits standard dimensional lumber used in common residential and light commercial framing, keeping the connector versatile across typical job site conditions.
• Rafter slope up to 45 deg. accepted - accommodates a wide range of roof pitches without requiring a separate or modified connector, supporting flexible roof design.
• No birdsmouth cut required for uplift loading - simplifies rafter preparation on applicable installations, saving labor and reducing the chance of cuts weakening the rafter.

Why This Product

• Engineered specifically for hip corner framing - the fixed 45 deg. connection angle is purpose-designed for this joint type, so installers get a connector that fits the application rather than adapting a general-purpose plate.
• ZMAX finish adds durability where it counts - the advanced zinc coating provides a higher level of corrosion resistance than standard galvanizing, making this connector a sound long-term choice in demanding framing conditions.
• Installation flexibility built in - with rafter slope up to 45 deg. supported and no birdsmouth cut needed for uplift loads, this plate works across a broad range of common roof configurations without compromising the connection.
• Made in the United States by Simpson - backed by the manufacturing standards of one of the most recognized names in structural connectors, providing confidence in consistent quality and performance.

Frequently Asked Questions

What is the purpose of the HCP2Z hip corner plate?

The HCP2Z is designed to connect a rafter or joist to double top plates at a 45 deg. angle, providing a secure hip corner connection in wood framing applications.

Is a birdsmouth cut required when installing the HCP2Z?

A birdsmouth cut is not required for table uplift loads; however, it may be required for download conditions. Refer to the installation guidelines to determine requirements for your specific application.

What fasteners are required to install the HCP2Z?

Installation requires (12) nails measuring 0.148" x 1-1/2". The connector is first attached to the double top plates, then the rafter is installed and nailing is completed.

What is the maximum rafter slope allowed with the HCP2Z?

The rafter may be sloped up to 45 deg. when installing the HCP2Z, providing flexibility to accommodate a range of common roof pitches.
