The MSC Multiple-Seat Top-Flange Connector is a precision-engineered solution for challenging hip and valley roof framing scenarios. Designed to support two valley connections without requiring a ridge member, the MSC simplifies installation and improves load distribution in multi-directional roof systems.

This connector accommodates a wide range of joist sizes, slopes, and skews, offering flexibility for unique framing layouts. Whether you're working with structural composite lumber or solid sawn joists, the MSC makes it easier to meet design demands without compromising structural integrity.

Ideal for residential and commercial construction, the MSC connector excels in situations that require customized load paths and multiple intersecting joists, making it a go-to solution for advanced framing professionals.

Features:

  • Dual Valley Connections: Supports two valley connections without the need for a ridge beam—great for hip/valley roof systems.
  • Top-Flange Design: Provides structural alignment and resists beam rotation for reliable performance.
  • Flexible Configuration: Accommodates a wide variety of joist sizes, slopes, and skews to match complex framing designs.
  • Customizable Sizing: Manufactured to suit your project’s specific requirements—reference the order worksheet for guidance.
  • Heavy-Duty Performance: Built from rugged materials to handle demanding structural loads.

Applications:

  • Hip and valley roof framing
  • Intersecting joist layouts in custom homes or commercial roofs
  • Projects requiring split-load valley configurations
  • Design scenarios with no ridge beam requirement

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
