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 are available in either two or four inch lengths. A 1/2" diameter drill bit is used for installation. The installation holes may be plugged with the accompanying plastic plugs or Energy Seal.
A typical six to eight inch round log end will require one 4? long or two 2? long Cobra Rods inserted within 4 inches of the butt end.
