Cobra™ Rods Instructions

(Printer Friendly Version Here)

Cobra Rods are effective against some kinds of termites. Cobra Rods are used internally in wood with a permanent or periodical moisture content above the fiber saturation point (30%) for poles, etc. The rate of application for Cobra Rods is dependent upon the volume of wood to be treated. The recommended load is up to 6 oz. Boric Acid per cubic foot of wood depending upon requirements for treatment. The loading should not be less than 2.0 oz. of Boric Acid per cubic foot of wood. Cobra Rods contain 1.45 times equivalent Boric Acid (BAE).

Inspections can be carried out every 5-8 years for Industrial wood and every 8-10 years for commercial wood. If reusable plastic plugs are used new rods may be inserted into existing holes during the re-inspection process and the same plugs tapped back into place. The angle at which the rods are installed should be at 45° for wood placed vertically into the ground. If the wood is decayed sufficiently to be condemned and no reinforcement is mandated, DO NOT install Cobra Rods. Be careful during installation to not cause unacceptable structural damage to the wood during installation of rods.

Cobra Rods are placed into holes drilled in wood at specific high risk locations (such as at the ground line or near joints and exposed end-grain) and are dependant upon moisture in the wood to work. The rods are positioned so that they are dissolved by the moisture in the wood and the desired loadings are distributed throughout the target area. For remedial treatments of existing decay, 6 oz. of Boric Acid Equivalent (BAE) per cubic foot of wood is recommended. For preventive treatments, 2 oz. BAE per cubic foot is sufficient. When treating exposed ends or joints, Cobra Rods should be installed within six inches of the exposed end or joint.

Directions for Use

Genics Cobra Rods are for treatment of pole structures, dimensional lumber (round stock, square stock) or any non-food contact wood. Cobra Rods are recommended for protection against fungal decay and insects. Cobra Rods can be used for all wood species.

To install Cobra Rods, the three step process is as follows:

1. Drill a hole at ground level (for posts and poles) using a 1/2" spade bit. Start the hole with the drill positioned horizontally. Once the bit is established, raise the drill to aim downward into the post at a 45° angle. Leave enough headroom to accommodate a 1/16" oversize plug.

2. Place the Cobra Rod into the hole. Never hammer the Cobra Rod during installation.

3. Insert the plug and push firmly to seat in hole. Hammer in plug until flush with surface.
