Abstract
A reel based closure device includes a housing, a spool positioned within the housing, and a knob that is operably coupled with the spool so that an operation of the knob causes the spool to rotate in a first direction within the housing. The spool has an upper flange, a lower flange, and a cylindrical wall disposed between the upper flange and the lower flange. The spool is rotatable in the first direction to wind a tension member about the spool's cylindrical wall when the spool is rotated in the first direction. The tension member has a first end and a second end positioned opposite the first end. The cylindrical wall has three holes through which the first end of the tension member is inserted to secure the first end of the tension member to the spool.
