Photo shows Cobra Rods and Cobra Rod Plugs. |
Cobra Rods 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. Cobra Rods are a deep green color and has a glass-like look and feel. When used for logs, the Cobra Rods can be "plugged" with caulking or chinking to aesthetically hide them. CobraRod Plugs are also available (included with the 2" 10 pack and 3" 12 pack of Cobra Rods). Cobra Rods can be used in logs, landscape timbers, deck joists, posts, and other places where moisture is present. The treatment cycle is 8 to 10 years if wood moisture is 20% or higher. Cobra Rods 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 dependent upon moisture in the wood to work.
Made in Canada.
Wood ends and joints are particularly susceptible to fungal attack and an appropriate size rod should be inserted within 3 inches of any end or joint in high-risk areas. Linear spacing along the grain should never exceed 15 inches on center and spacing across the grain should not exceed 6 inches on center. After the rods are in place, the holes should be plugged using a plastic plug, wooden dowel, caulk, chinking or wood putty. The treated area can be painted, stained, or coated with any appropriate finish.
Application Steps
- Drill appropriate size holes to accommodate the number and size of CobraRods required. Drill hole size should be approximately 1/16” larger than rod size. Plug size should be approximately 1/16” larger than hole size. (Consult the recommended Application Rate Table for this information).
- Insert the CobraRods into the hole or holes.
- Plug the hole with a plastic plug, wooden dowel, caulk or wood putty.
