Cobra Rod
Cobra Rods will significantly extend the service life of all types of wood, including wood poles. This highly concentrated glass rod outperforms by a factor of 2 to 1 all other liquid water-soluble wood preservatives, which tend to leach rapidly. The active ingredients are internationally recognized and approved as preservatives by CWPA, AWPA and BWPA. Not only can they be used to control ground line rot they can also be used to control pole-top and cross-arm rot. They use safe, effective borates, which activate at the critical moisture level, are easily installed and outperform all other rods.
We've got the right stuff
The borates in Cobra Rods are considered one of the chemical groups effective in controlling and stopping fungal decay and many insects - at concentrations that are not even close to poisonous for humans and other mammals.
Cobra Rods have a unique combination of active ingredients which, unlike all others, give protection against both fungal families, basidiomycetes and ascomycetes. They activate at 23% to 30% moisture levels, the same levels at which decay begins in wood. Cobra Rods are clean to handle, leaving no chalky residue on hands or clothing. They also resist breakage and are applied in drilling patterns that preserve pole strength.
Manufacturer's recommendations and PMRA/EPA label
directions guide the installation of the rods. In brief, the steps are:
- Drill the least diameter possible hole to accommodate pre-determined number and diameter of Cobra Rods
- Insert suitable size and number of rods
- Seal holes with treated plugs
