Perfect part when the pipe would be a little longer! Thanks to the excellent good pictures with the dimensions, I had the certainty that my sunshade is fit. So it fits each OBI sunshade Cocoa Beach Green Ø 350 cm! ! ! The hole pattern fits exactly to the Aufschraubplatte for OBI sunshade Cocoa Beach. Base plate is well made and very stable, I have only prolongs the tube, so that I can keep smaller dimensions for the concrete foundation! Turning the screws into the holes, from the bottom silicone tube over the threaded slide (so the concrete does not stick to the Bolzenewinde remains and is destroyed rotate the bottom Platt thread when out) in concrete, let it harden and studs can easily unscrew ;-)
