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.

Post Guard instructions

Use a ½” drill bit to drill hole.	Drill hole to a depth of at least 3 ¾”.	Clean out the hole and insert the Cobra Rod.	Insert the plastic plug into the hole.
Using a screw driver twist the plug clockwise.	Make sure the top of the plug sets about ¼” below the surface of the wood.	Fill the hole with appropriately colored Energy Seal.	Smooth with tool or finger. After a few hours the Energy Seal may be stained to match the surrounding area.
