Torchwood One found the Magna-Clamps buried in a crashed spaceship at the foot of Mount Snowdon. They were then removed and taken back to Torchwood Tower. Yvonne Hartman showed the Magna-Clamps to the Tenth Doctor and Jackie Tyler during their tour, (TV: Army of Ghosts) and later on during the Battle of Canary Wharf the Doctor and Rose Tyler used the Magna-Clamps to hold onto a wall when the Void was open. This stopped them from falling into the Void until Rose let go and almost fell in. (TV: Doomsday) A set of Magna-Clamps was present in the UNIT Black Archive. (TV: The Day of the Doctor)
