The Grav-Tether is a gadget created by Pollyx Industries in Into the Nexus used by Ratchet. It is fired between two grav targets to create a purple grav-stream between them, in which the user can float between the beams in a specific direction. This allows Ratchet to reach otherwise inaccessible areas.
