A slider is operably coupled to the bracket and includes a knob that extends through the opening that is defined by the bracket. The slider defines a groove and a notch. A barrier member is operably coupled to the slider and is selectively coupled to the retention features of the bracket. The barrier member includes a spine that is slidably disposed within the groove defined by the slider and selectively engaged with the notch.
