Grayson, Neil and Simon are able to secrete a sticky thread-like substance from their hands. They can shoot these out to form webs that they can use to climb on, and can use these webs in order to trap victims or to cling victims upon walls. They are also able to use this ability to swing from building to building, by shooting out webs from their hands to hang and swing on. They can never become entrapped in the webs themselves. However, they can only produce this substance from their fingers.
