Section 6.5: Adding Foam Plug Assembly to the Telescoping Poles
Each 20m-6m telescoping pole tip requires a breathable foam plug to allow for venting of the
EHU. The foam plug assembly (PN 70-1007-01) in Figure 6.51 consists of a special UV re-
sistant foam plug material, a SS screen, and a vinyl cap.
The foam plug and SS screen is installed inside the vinyl cap at the factory.
The fit of the vinyl cap on the pole tip is purposely very tight, so that the foam plug assembly will
stay in place. Before attaching the foam plug assembly, spread a small amount of dish soap
around the inside edge of the vinyl cap as shown in Figure 6.52. This helps the housing slide on
easily, and the soap will eventually evaporate, leaving you with a firm interference fit.
Insert the foam plug assembly onto the telescoping pole tip as shown in Figure 6.53. Be sure
that the plastic housing bottoms out on the pole tip.
Repeat for the other telescoping pole tip.
