By: Georgia-pacific Cda  09-12-2011

A proprietary manufacturing process produces properties that allow designs with excellent seismic and wind-resistance performance. Our proven edge- and end-coating process for moisture resistance virtually ensures dimensional stability and job site durability.

Sizes and Weights
Depth 9-1/2" 11-7/8" 14" 16"
Weight (PLF) 3.0 3.7 4.4 5.0
Thickness 1-1/8"
Length 12'


  • Vertical Load - Rim doublerstarter joist, or starter joist with blocking, supports 24" o.c., 4,850 PLF
  • Horizontal Load - Lateral seismic or wind load, 200 PLF using a load duration factor of 160%. With 1/2" lag or through bolt attaching ledger to rim board, 350 lbs. lateral load per bolt
  • Lateral load for nails in wide face of rim board - Design per 1997 NDS using Douglas Fir-Larch values

Connection Requirements

  • Connecting to joist - Face-nail rim board to each joist with two (2) 8d nails, one into top and bottom flange.
  • Connecting to plate - Toe-nail rim board to wall plate with 8d nails at 6" o.c. or 16d nails at 12" o.c.
  • Connecting to subfloor - Attach floor sheathing to rim board per building code or structural panel manufacturer's specifications (closest on-center nail spacing is 6"). For lateral seismic or wind shear transfer of up to 200 PLF, use 8d nails at 6" o.c.
  • Connecting to other rim boards - Face-nail rim boards together at corners with three (3) 8d nails.
  • Attaching ledgers - To attach a ledger, use 1/2" through bolts with nuts and washers or 1/2" lag screws (minimum length of 4") with washers. Maintain 2" edge distances on ledger and rim board. When using lag screws, drill 5/16" lead holes in rim board and 1/2" holes in ledger. Caulk holes with high quality caulking immediately before inserting the bolts or lag screws. Caution: The lag screw should be inserted in a lead hole by turning with a wrench, not by driving with a hammer. Do not over-torque lag screws. Over-torquing can significantly reduce the lateral resistance of the lag screw.
