An equipment support for attaching equipment to an aircraft comprises a gripper foot having a T-shaped slot that engages a track mounted to the aircraft floor. The gripper foot is mounted to a trunnion mount that enables the gripper foot to rotate freely about a vertical axis so that the gripper foot can negotiate curves along a non-linear track. The trunnion mount is mounted to the equipment support frame by means of a horizontal pivot. The horizontal pivot is held against rotation below a predetermined load by a torque-resisting element. If the floor track is warped, for example during a crash, the twisting loads transmitted from the floor track to the gripper foot overcome the torque-resisting element, which allows the trunnion mount and gripper foot to rotate with the floor track thereby allowing the gripper foot to remain attached to the track without imparting excessive loads on the track, gripper foot, or equipment support frame.
