Borate Impel rods
Cobra™ Rods are a way to spot treat decay prone areas such as log ends that are already coated with a finish. Once inserted into damp or wet wood the borate / copper complex in Cobra Rods dissolves spreading the active ingredients into areas surrounding the rod. This eliminates active decay fungi and helps prevent rot for 8 to 10 years. Cobra Rods are available in two different sizes. A fitting drill bit is used for installation. The installation holes may be plugged with the accompanying plastic plugs or Energy Seal.
A typical 15-20 cm round log end will require one long or two shorter Cobra Rods inserted.
