SuperHooks are required to securely install a LT1 version 2 FlightDeck onto a set of LT1 V-racks. SuperHooks securely clamp the FlightDeck to the V-racks. They come in a set of 4. If you intend to install a Yepp Maxi seat on your LT1 version 2 FlightDeck, you will need two sets of SuperHooks for a total of 8 hooks.
SuperHooks cannot be used on wooden SnapsDecks and are not required for the newer LT2 FlightDeck found on 2016 EdgeRunners, Leaps and Cargo Nodes.
