Snare cable

Snare Cables were a type of Graske weaponry used to capture individuals. (WEB: The Alien Files) They shot out cables which would latch onto the target, allowing them to be teleported away. The could also be reversed, allowing the individual to be returned. Krislok used his to capture Maria Jackson, allowing him to remove her from time into Limbo. He later tried to captured Alan Jackson, but was captured instead. (SJA: Whatever Happened to Sarah Jane?)
