A cap (3)is placed on the hollow profile (2) anchored in the ground. A snow-post (5) inserted into the hollow profile passes through the cap in a guide pipe (4) fitting into the hollow profile. The inside of the guide pipe has at least one axial groove (7) starting from the underneath end surface (8) and opening into a peripheral groove (9).A radial bolt attachment (6) to the snow-post near its bottom end fits into the groove. The guide pipe forms a support for the snow-post to prevent it turning. |
