An expandable band includes one or more expandable links and one or more expansion mechanisms. The expandable link is movable between expanded and contracted positions. The expandable link is biased toward the contracted position. The expansion mechanism can be manipulated to transition the expandable link between the expanded and contracted positions, thus expanding and/or contracting the expandable band. The expandable links may be X links, pantographs, and/or other linkages. The expansion mechanism may include one or more restrictors operable to restrict expansion of the expandable band. The expansion mechanism may also include one or more lock mechanisms operable to prevent and/or resist contracting of the expandable band.
