1. An apparatus comprising:
a support member;
a flexible elongate member to extend and retract through an opening in the support member; and
a stop member including a region having a first surface to interface with the flexible elongate member, the stop member to directly engage a second surface of the support member surrounding the opening to limit a distance with which the flexible elongate member extends through the opening, the stop member to cooperate with the second surface of the support member to maintain a gap between the first surface of the region of the stop member and the second surface of the support member, a width of the gap being equal to or greater than a thickness of the flexible elongate member, the stop member being elongate along a central axis, the first surface corresponding to an inset surface of the stop member positioned between first and second protruding surfaces of the stop member, the inset surface a first distance from the central axis, the first protruding surface a second distance from the central axis greater than the first distance.
