a first engagement member coupled to the support; and
a translatable column defining a longitudinal axis, wherein
the translatable column is rotatably and translatably mounted relative to the support;
the translatable column is translatable between:
a first position in which the translatable column and the first engagement member are spaced apart from one another such that the translatable column is rotatable about the longitudinal axis, and

the barrier member comprises one or more biasing members configured to bias the translatable column to the first position;
the support comprises a first movement mechanism defining an extent of translation of the translatable column, the first movement mechanism comprising a first end member and a second end member and the one or more biasing members;
the one or more biasing members are located between the first end member and the second end member;
