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