RBC Model No. Type of Connection Bending Angle Fasteners 4 Typical RBC Installation to CMU Block 3 2 Typical RBC Installation The RBC Roof Boundary Clip is designed to aid installation and transfer shear loads between the roof diaphragm and wall top plates. 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. MATERIAL: 20 gauge FINISH: Galvanized INSTALLATION: Use all specified fasteners. See General Notes. Field bend to desired angle one time only. See flier F-RBC04 for more information on installation and code requirements. CODES: See page 12 for Code Listing Key Chart. The RBC installed to blocking resists rotation and lateral displacement of rafter or truss.
