2" x 8" x 12' MCA #1 Pressure Treated Lumber

MCA stands for Micronized Copper Azole. MCA is a copper-based wood preservative used in pressure treated lumber allowing for residential installations above ground, ground contact, or freshwater contact. Lumber pressure treated with MCA can be used in interior applications as long as all construction debris, including sawdust, is collected and disposed. Do not use in instances where the lumber could come in contact with food or animal feed. To keep the integrity of the pressure treatment, coat all cuts and holes which expose untreated wood with an end-cut preservative before installation.
