Thanks for writing in. Sure, you can combine the extension with the joint. The extensions are mostly used to give you clearance over deeper window sills or hard-to-reach spots. If that's not a factor for you, and the only thing you have to worry about is height, then I think you can get away with just the 39-078L and a pole. Let me know what you think. |
