Wood Plugs

Wood Plugs are either 5/8" or 7/8" diameter by 1" long. They are made of hardwood and treated with Copper Napthenate for long durability. The plugs are tapered on one end for easy application. Wood plugs can be used anytime the installation is horizontal, vertical down or diagonal down. However, if the installation is vertical up or diagonal up, use the plastic plugs as they have threads to keep them in place.

Plastic Plugs

Plastic plugs are also known as Re-Plugs. They are removable for inspection and maintenance. They come in black, beige or bright yellow for easy identification in places like bridges, marinas or docks. While they are threaded, they can be tapped in with a hammer, but you need a special tool to remove them. The tool is about $7.00. Plastic plugs should be used whenever IMPEL Rods are installed in ground contact where they will need to be replaced every 5 - 10 years.
