Our Split flash collars are made from solid cast aluminum and are designed with a split in the circle. This feature allows for replacement of the flash collar without the time and expense of hiring a company for replacement or a bucket truck being needed. This style of flash collar measures 14rdquo; in diameter and can fit flagpoles with a butt or base diameter of 3rdquo;, 4rdquo; 5rdquo;, 5.5rdquo;, 6rdquo; or 7rdquo;. The satin finish will add that finishing piece to your flagpole display. If you are looking for another finish or color, please contact us and we will be happy to help you find the component you are looking for.If the split style flash collar isnr’t the design you are looking for, Carrot-Top Industries also has the more traditional, one-piece flash collar styles available. Please keep in mind that while the one-piece styles are more cost-effective, they will require a more complex installation process. For any additional outdoor flagpole components, please browse our accessories page. As with any grand flagpole display, an American-made United States flag pairs beautifully with these accessories. Browse our Outdoor American flags, including the Beaconreg; Nylon and Patriarchreg; Polyester American flags, to find the material and size to fit your needs.
