ABSTRACT:
An attachment device for coupling one or more restrained members to a frame. In at least one embodiment, the attachment device may be configured to attach one or more turbine combustor liners to a carrier. The attachment device may include a body rotatable about an axis of rotation and including one or more arms for grasping an edge of at least one restrained member. A fastener may be coupled to the body for coupling the body to a frame. The attachment device may also include a retainer for preventing the fastener, which may be a threaded bolt, from becoming disengaged from the attachment device and traveling downstream in a turbine. An alignment device may be included for facilitating rotation of the body of the attachment device and engagement the arms with edges of retrained members. The alignment device may include an alignment indicator indicating a position of the arms.
