Simpson Strong-Tie Ridge Rafter Connector

Reliable Alignment and Secure Fixing for Sloped Roof Rafters

The Simpson Strong-Tie RR Ridge Rafter Connector is purpose-built to ensure precise alignment and structural connection of rafters at the roof ridge. Suitable for any rafter slope up to 30°, this connector simplifies installation by offering pre-defined nail locations and reducing the risk of misalignment—making it ideal for pitched roof systems in residential and light commercial construction.

Key Features

• Slope Compatibility up to 30°
  Designed to accommodate a wide range of common roof pitches, the RR connector maintains secure rafter alignment at the ridge line for slopes up to 30°.

• Controlled Alignment and Fastener Positioning
  Pre-engineered fixing points ensure correct nail placement, improving build consistency and structural integrity.

• Back-to-Back Installation Support
  For dual-sided applications, the minimum required ridge board width is 38mm, ensuring enough bearing and fastening surface for opposing rafters.

• Corrosion-Resistant Finish
  Manufactured from pre-galvanised mild steel, the RR connector provides durable performance in internal or protected roof structures.

Benefits

• Improves Structural Consistency
  Reduces site variation by standardising rafter alignment and nailing patterns, ensuring each rafter pair meets correctly at the ridge.

• Speeds Up Construction
  Clearly marked nail locations and easy positioning speed up roof framing, helping meet tight build timelines with fewer errors.

• Cost-Effective Strength
  Offers a simple yet robust solution for ridge joint reinforcement without the need for custom cutting or complex bracketry.

• Compatible with Timber Roof Framing
  Ideal for timber-framed roofs in domestic and light commercial projects where traditional rafter construction is used.
