Abstract: A built-in cooking hob includes a main body configured to be installed in an opening of a counter top. An upper plate abuts a peripheral edge of the opening, and is fastened to the main body. The upper plate includes a lower face having a plurality of hinged elements configured to assume a first configuration substantially orthogonal to the upper plate and a second configuration substantially parallel to the upper plate. Removable fasteners are disposed between the hinged elements and the main body in the second configuration for fastening the main body to the upper plate.
