Abstract
A reel based tensioning device includes a housing, a spool that is rotatably positioned within the housing, and a knob member that is operably coupled with the spool to cause the spool to rotate in a first direction within the housing and thereby wind a tension member about the spool. The reel based tensioning device also includes a load holding mechanism that is coupled with the spool and that is configured to rotate the spool in the first direction within the housing and to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from about the spool. The reel based tensioning device further includes an audible component that is configured to produce an audible noise responsive to operation of the knob member to signal an adjustment of the tension member.
