I have two Flag Pole Buddies, one on either side of my rear ladder. To do this must be differing sizes, see their web site and you will see which sizes install which direction to allow this. I use them for flags, WiFi repeater antenna, and ham radio antenna masts. Great product. So easy to put up and take down. Tight no rattling or noise. I have used them for several years.
