    Abstract: A fingerboard has a first portion configured to receive a first pipe and a second portion configured to receive a second pipe.

The pipe receiving space of the fixed section is sized for drill pipe while the pipe receiving space of the movable section may be the same size as the pipe receiving space of the fixed section or a different size than the pipe receiving space of the fixed section. The movable section has a first and a second pipe receiving spaces. The second pipe receiving space may be larger than the first pipe receiving space. A hinge moves the movable section to selectively locate the first pipe receiving portion and the second pipe receiving portion adjacent to the fixed section.
