It was also used in Order of the Phoenix by Fred and George when they forced Montague, the Slytherin Quidditch captain and a member of Dolores Umbridges' Inquisitorial Squad, into it when he tried to take house points from Gryffindor. Draco then learns of Montague's experience, discovering transportation is possible between the two Cabinets and the other is located in Borgin & Burkes. In Half-Blood Prince he manages to repair the broken one at Hogwarts so as to transport the Death Eaters into the highly secured castle.
