Product Description

11-7/8" RFPI-20 I-Joists are supplied through our Boise, Idaho lumberyard for multi-family framing throughout the Treasure Valley. This highly efficient 1-3/4" flange configuration provides clear-span structural support for everyday residential runs without adding unnecessary material bulk. They arrive flat and uniform, ensuring a level subfloor profile and cutting layout prep time. This series serves as a direct equivalent to Weyerhaeuser TJI-110 and Boise Cascade BCI-5000.
