Street Pole Banner Installation
Street pole banners are installed onto banner arm hardware which is fixed to a lamp post or pole of some sort. There are a few different kinds of banners brackets on the market, all of which are relatively similar
Fixed Street Pole Banner Brackets
For these brackets, it is very important to measure your poles well prior to ordering

It is imperative to use a zip tie to attach the inner grommets to the banner bracket, unless you have finials at the end of the banner bracket to prevent the banners from sliding off.
Adjustable Street Pole Banner Brackets

It is imperative to use a zip tie to attach the inner grommets to the banner bracket, unless you have finials at the end of the banner bracket to prevent the banners from sliding off.
Street Pole Banners are subject to all kinds of harsh weather conditions. The longevity of a street pole banner is largely determined by the way it was installed. Green Valley Flags does not provide a warranty on its street pole banners specifically because the installation method plays a major role in any potential material failures that may present in the future.

My installers always prefer to use Jr. Windspill banners. They last a very long time and they come in both static and adjustable options. This store sells the fixed option online but they carry the adjustable version too and if you call them they will arrange it for you. Our installers usually get the adjustable one which you can see in the pic. The arms are fiberglass so they're strong and flexible too.
