Actual: 1-1/2" x 3-1/2" x 8'

KD Douglas Fir #2&Btr S4S is kiln-dried lumber milled from Douglas Fir, a species known for its strength, stability, and workability. The #2 and Better grade ensures each board is at least #2 quality, with some pieces of higher grade mixed in, providing dependable performance for framing, beams, and general construction. Kiln drying reduces the lumber’s moisture content, improving dimensional stability and minimizing shrinkage or warping. Surfaced on four sides, the boards are uniform, smooth, and ready for installation.

With its combination of reliable strength, reduced moisture content, and ease of handling, KD Douglas Fir #2&Btr S4S is a preferred choice for builders and contractors. It is commonly used in residential and commercial framing, load-bearing structures, and other projects where both durability and stability are important.
