CobraRods are a safe, Environmental Protection Agency (EPA) approved decay protection and prevention system for wood. They are a wood preservative, fungicide, and insecticide that's safe to handle and made entirely of a unique Boron and Copper Hydroxide complex. The addition of Copper Hydroxide provides extended protection from fungus species not affected by borates, effectively providing more protection then Impel Rods.

CobraRods take the form of a solid cylindrical rod that is approximately 7/16" in diameter (use a 1/2" drill bit for installation) and comes in 2" and 4" lengths. The rod is a deep green color and has a glass-like look and feel. When used for logs, the rods can be "plugged" with caulking or chinking to aesthetically hide them. CobraRods can be used in logs, landscape timbers, deck joists, posts, and other places where moisture is present. Treatment cycle is 8 to 10 years if wood moisture is 20% or higher. CobraRods are placed into holes drilled in wood at specific high risk locations (such as at the groundline or near joints and exposed endgrain) and are dependant upon moisture in the wood to work.
