Gutter-auxiliary equipment, has front mounting section, which is inserted and fixed in hollow bulge of gutter, where front mounting section has locking head, which provides locking connection in hollow space of hollow bulge

摘要

The equipment (1) has an elbow section (2), which partially surrounds an outer contour of a cross section of a gutter, and a front mounting section (4), which is inserted and fixed in a hollow bulge of the gutter. The front mounting section has a locking head (15), which provides a locking connection in a hollow space of the hollow bulge. The locking head has a symmetrical cross section such that extraction force for extraction of the front mounting section in the bulge is equal to press-in force required for pressing the front mounting section in the bulge.
