About the manufacture: Flags Poles And More has our own brand of American Flags, State Flags and we even make custom flags. We also sell flagpole related products. We pride ourselves in American Made Flags, and selling the best flagpole products.About the product: These rotating flag rings are made by Flags Poles And More. Our brand is printed on the product and/or packaging. Flagpole mounting rings are proudly made in the USA. These rings are met for 1 inch outside diameter flagpoles.Rings have a rotating anti-wrap feature that allows the flag to move independently from the pole, helping prevent the flag from wrapping around the pole. Works on any standard 1" flag pole. WHAT THIS MEANS IS THE OUTSIDE DIAMETER OF THE FLAGPOLE IS 1 INCH. So if you were to measure the diameter from one end to the other end of your flagpole (at the farthest points not the length of the whole flagpole) it CAN'T be larger than 1 inch on the outside diameter. These rings go around the outside of your flagpole. Flags Pole And More has taken a picture of a butt end of a flagpole that would slide into a 1" flagpole bracket (this flagpole and bracket are sold separately). As you can see in the picture the pole is just under 1 inch and will work perfectly with these 1 inch rotating flagpole rings. The next photo is of the 1 inch rotating flagpole ring measuring from one end to the other, as you can see the diameter measures 1 inch. If your flag pole is larger than 1 inch these will NOT WORK. Know as Flag Clips, Flag Holder, Flag Snaps, Rotating Flag Rings, Flag Mounting Rings, etc. Pole and Flag in the pictures ARE NOT included. Size: 1" (For 1 inch outside diameter flagpoles) Color: White Pack: Comes with 2 rotating rings total Made in: USAMade by Flags Poles And More
