This is a 0.47 inch diameter, NOT 0.5 inch. They sit very loosely in the spring cone and are therefore unsafe. Update: The seller has changed the description to reflect the actual width of this product, however all explanatory information still indicates an inaccurate 1/2" measurement and conflicts with the actual width of 0.47". I have changed my rating from 1 to 3 stars to reflect the seller's efforts and customer service. The bars remain useless to my need for a true 1/2" width.
