118's hanger was ruled illegal as it was deemed to be "grappling" on the bridge. A specific definition was posted in the relevant thread, seen here:

It would therefore be a violation of [G10] when used, and be penalized accordingly. We were told it was not the GDC’s intention that teams utilize the features at the edge of the bridge to hang or lift off of during a balance.
During a break in matches at the beginning of the day, the head ref explained this ruling to the crowd. During this he read the following definition for Grapple: “The use of a tool to catch, hold, or rake to gain a physical/mechanical advantage”.
In our conversations with the head ref he expanded on this definition, talking about devices which react against multiple surfaces to create a moment or torque.

179's hanger is designed such that, when functional, they will be wholly supported by the bridge from above. My personal opinion is that their hanger falls into neither the grabbing, grasping, grappling, nor attaching category (listed under [G10]) and is therefore legal. However, if what Alex said is true and 179 never successfully hung from a bridge, then we will likely only see a ruling at SFR.
That being said, in the event that 179's hanger is deemed illegal, grasping seems like the least likely of the 4 grounds on which to rule it illegal.
