Abstract: A buckle assembly includes a first plate and a second plate defining a gap therebetween. A button assembly defines a slot aligned with the gap, and is coupled to the first plate and the second plate for movement along a longitudinal axis of the first plate. The button assembly includes a door transversely moveable relative to the longitudinal axis between a closed position covering the slot and a retracted position spaced from the slot. The door includes an angled ledge, that directs fluid through at least one aperture in a sidewall of the button assembly when the door is in the closed position. A block is disposed within the gap. The first plate and the second plate define undulations extending along the longitudinal axis and into the gap. The block mates with the undulation in the first plate and the second plate to fill the gap.
