RBC Roof Boundary Clip

RBC

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.

Material

  • 20 gauge

Finish

  • Galvanized

Installation

  • Use all specified fasteners; see General Notes
  • Field bend to desired angle — one time only
  • See flier RBC Roof Boundary Clip (F-C-RBC) for more information on installation and code requirements

Load Tables

  1. See General Notes for Straps and Ties.
  2. Allowable loads are for one anchor attached to blocking a minimum of 1 1/2" thick.
  3. RBC/RBCP can be installed with up to a 3/4" gap and achieve 100% of the listed load.
  4. When attaching to concrete, use (3) 1/4" x 1 3/4" TTN2-25134H Titen® 2 screws.
  5. RBC/RBCP installed over 1" foam board has a load of 395 lb. (160) in a parallel-to- wall (F1) load direction for Douglas fir. For SPF, the load is 340 lb.
  6. RBC/RBCP may be installed over 1/2" structural sheathing using 0.148" x 1 1/2" nails with no load reduction.
  7. Fasteners: Nail dimensions in the table are listed diameter by length. Titen® 2 screws are Simpson Strong-Tie® masonry screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
