Anti-wrap Design: The 360 degree free rotation stainless steel ring ensures strength and hardness. At the same time, the excellent anti winding performance can make the flag fly freely in the wind and prevent the flag from winding the flagpole. Durable Design: The high-quality aluminum alloy ring body and stainless steel ring design make the flagpole ring durable, light, no rust, no flading, no deformation and no cracking. They can adapt to all kinds of harsh environments. Adjustable Screw: Use 2 screws to adjust the diameter of flagpole ring. The long screw is suitable for 0.75 inch flagpole, while the short screw is suitable for 1 inch flagpole. You can install flagpole in the 0.75-1.02 inch diameter range. Hook Design: 2 pack aluminum mounting rings and 2 piece aluminum hooks for you. You can link the flagpole ring hole and the flag with the hook.
