Trunnion pins protruded from the sides of large payloads carried in the Space Shuttle payload bay. They locked into mounts on the payload bay sill and secured the payload in place for the primary structural mating of the payload and the orbiter. The flight support system cradle for the Hubble Space Telescope, for example, was attached to the payload bay via trunnion pins, as were Spacelab and International Space Station laboratory modules. NASA released this trunnion pin from the Hubble equipment inventory.
