Bathook

The batclaw, bathook or bat-grappling hook was what Batman and Robin called their personal hooks, which were attached to a rope.

The Batjet was equipped with its' own bat-grappling hook, while the Dynamic Duo normally carried bathooks in their utility belts. Some of their Bathooks were able to be shot out of their Bat-Grappling Gun, so as to send the Batline an even greater distance.
