RBC Roof Boundary Clip


On This Page

The RBC roof boundary clip is designed to aid installation and transfer shear loads between the roof diaphragm and wall. The locator tabs make proper location of the clip easy. The RBC can be used on wood or masonry walls and will handle roof pitches from 0/12 to 12/12. The RBC is available with prongs into one side (RBCP) for pre-attachment of the part to a block at the truss plant.


  • 20 gauge


  • Galvanized


  • Use all specified fasteners; see General Notes
  • Field bend to desired angle — one time only
  • RBCP should be pressed on to blocking, not hammered
