1. A reel based closure device comprising:
a housing having an interior region;
a spool rotatably positioned within the interior region of the housing;
a tightening member rotatably coupled with the housing and operably coupled with the spool such that an operation of the tightening member causes the spool to rotate within the housing in a first direction to wind a tension member about the spool;
a central boss that extends axially in the interior region of the housing, the central boss having a distal end that includes or defines an axially extending gap; and
a reinforcement spring positioned within the axially extending gap of the central boss, the reinforcement spring being configured to reinforce the central boss.
