RBC Roof Boundary Clip

Installation

View step-by-step installation instructions

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 F-RBC for more information on installation and code requirements.

Codes: Also see Code Reports.

The RBC installed to blocking resists rotation and lateral displacement of rafter or truss. Code references:

IRC 2000/2003/2006, R802.8 Lateral Support
IBC 2000/2003/2006, 2308.10.6 Blocking

Blocking allows proper edge nailing of sheathing. Code references:

IRC 2000/2003/2006, Table R602.3(1), footnote i
IBC 2000/2003/2006, 2305.1.4 Shear Panel Connections

U.S. Patent 7,549,262
The RBC is available with prongs into one side (RBCP) for pre-attachment of the part to a block at the truss plant. Refer to technical bulletin T-RBCP for more information.

Allowable loads are for one anchor attached to blocking minimum 1 1/2" thick.
RBC can be installed with up to 3/4" gap and achieve 100% of the listed load.
Allowable loads have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
When attaching to concrete use three 1/4 x 1 3/4" Titen® screws.
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.
NAILS: 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
