After a quick nspecting the Ball Bearing Windsock Frames upon receiving it I found the rubber top cap is possibly truly the weakest link for this other than that, seeming great product. When the rubber cap fails it will expose the bearings to eventually leading to bearing failure. I plan to correct this for problem prior to its failure. Other than that, prior to installation this product looked to be well constructed. The wire ties were of poor quality and no extras ones included. The welded structure itself looked to be made well and powder coated.
