RBC Roof Boundary Clip

RBC

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.

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. Allowable loads are for one anchor attached to blocking minimum 1 1/2" thick.
  2. RBC can be installed with up to 3/4" gap and achieve 100% of the listed load.
  3. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  4. When attaching to concrete use (3) 1/4" x 1 3/4" Titen® screws TTN2-25134H.
  5. RBC installed over 1" foamboard has a load of 395 lbs. (160) in a parallel to wall (F1) load direction for Douglas Fir. For SPF, the load is 340 lbs.
  6. RBC may be installed over 1/2" structural sheathing using 10d x 1 1/2" nails with no load reduction.
    Fasteners: 10d x 1 1/2" = 0.148" dia. x 1 1/2" long.
    TTN2-25134H = 1/4" x 1 3/4" Titen 2;
    TTN2-25214H = 1/4" x 2 1/4" Titen 2.
    TTN25134H = Titen 1/4" x 1 3/4" and
    TTN25214H = Titen 1/4" x 2 1/4" may also be used at full table loads.
