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 are two inches in length. A 1/2" diameter drill bit is used for installation. The installation holes may be plugged with the accompanying plastic plugs or wood caulk.
A typical six to eight-inch round log end will require two 2” long Cobra™ Rods inserted within 4 inches of the butt end.
