The gutter (18) is supported by and secured to cradles (2) by a set of fasteners each comprising two plates (4, 6), one plate being secured to a gutter fixing part (8) and the other plate being secured to the cradle. At least one of the two plates contains a number of holes (12) which are evenly distributed in the height direction for receiving a fixing part (18) used to secure the two plates together. The fasteners can be adjusted individually in order to set the gutter pitch. An independent claim is also included for a gutter for use in combination with the support device, comprising an open dihedral-shaped base (40) with an angle of 90-160 deg. and a pair of side walls (34, 36) extending at an angle of 90-120 deg. relative to the base. |
