I've had two Poles and Holders flagpoles. I've managed to break them both and now looking to replace the last one. Corky is great, love the guy and he's fixed mine numerous times all at no charge and ...
I use a flagpole from Telepole, 30ft will handle 3 flags and lowers using attached push pins. Mine is the Superior 3. Here is a link, http://www.tele-pole.com/flagpoles/superior-3-flagpole/ A little more expensive but has a 15yr warranty, use ours at Nascar races with 3 flags. They also have 20 and 25 ft poles.
