Cobra Rods
Borate Wood Preservative

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 7/16” in diameter and two inches long. A 1/2” diameter drill bit is used for installation. The installation holes may be plugged with the accompanying plastic plugs and hidden with Energy Seal. A typical six to eight inch round log end will require two 2” long Cobra Rods inserted within 4 inches of the butt end.
