Post Guard (known as Cobra Rods) Borate Rods
Post Guard 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 the 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.
Post Guard 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 rods inserted within 4 inches of the butt end.
