Abstract: A door actuation system may include an actuation device to move a first door leaf and a second door leaf between an open and a closed position. The actuation device may provide an open preload force in the open position. The actuation device may provide a closed preload force in the closed position. The system may include one or more of: a first engagement member that may contact the actuation device and may allow movement of the actuation device to adjust the open and closed preload force; or the actuation device may be coupled with the first door leaf by a first rod and the second door leaf by a second rod, at least one of the first or second rod may adjust a length of the first or second rod to maintain the open preload force in the open position and the closed preload force in the closed position.
