The 11-7/8" RFPI-40 I-Joist is a higher-performance engineered wood joist commonly used in residential floor systems where additional capacity is required beyond lower-series I-joists.
RFPI-40 is an industry-recognized equivalent to Weyerhaeuser TJI-230 and Boise Cascade BCI-6500, making it compatible with plans and specifications calling for those joist series.
We stock 11-7/8" RFPI-40 I-joists in Boise for immediate pickup or scheduled Moffett delivery throughout the Treasure Valley and surrounding areas.
