We describe all the localization observables of a quantum particle in a one-dimensional box in terms of sequences of unit vectors in a Hilbert space. An alternative representation in terms of positive semidefinite complex matrices is furnished and the com-mutative localizations are singled out. As a consequence, we also get a vector sequence characterization of the covariant phase ob-servables.
