Wood Plugs are used to seal holes after ½ and ¾ diameter Bor8 Rods are inserted. The plugs are 1/16” larger than the prescribed hole which is 1/16” larger than the Bor8 Rod.
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.
