Made of galvanized steel. Only the upper part (51 cm) is inserted into the lower, concreted part of the ground stem (40 cm) to install a sunshade. Thus, the ground stem protrudes 32 cm from the ground and shields up to ?ÿ 60 mm. If no sunshades are needed, the upper part is removed and the hole is closed with a closure cover at the bottom. The required concrete foundation for the ground stem must be at least 50x50x50 cm and guarantees a safe position of the sunshade. Weatherproof! Incl. cover lid! Stainless steel!
