After repeatedly fell over us our umbrella (be bent) with umbrella stand, quickly came the decision to look for a ground socket out. We discovered this here - and did not regret it! Easy to screw, budge, you may well drum mowing around and they do not overlook (accident) because she is so beautiful orange! Our screen has a rod diameter of 4.8 cm, (now now) screen with a crank and not be bent - but also fits perfectly! Highly recommended, 5 *
