The 2×4 is the everyday workhorse of light-frame construction: wall framing, plates, blocking, repairs, and small structural assemblies. This #1 Douglas Fir-Larch stock combines useful strength with kiln-dried, surfaced-four-sides consistency. Stocked for in-store pickup; verify grade, spacing, and code requirements before building.

The 7/16-inch OSB panel is a common wall-sheathing choice and may serve in rated roof assemblies when its stamp and framing spacing allow. Oriented strands give the panel consistent structural performance across framing packages. Stocked for in-store pickup; verify the span rating, strength axis, fastening, and exposure requirements.

Ground-contact 2×4 treated Douglas Fir is useful for fence rails, deck blocking, small exterior frames, and repairs exposed to recurring moisture or soil-adjacent conditions. Its CA-C .15 treatment is intended for ground-contact service. Stocked for in-store pickup; use compatible fasteners and verify the required use category.
