a dial with a first projection and a second projection on an underside of the dial to engage a pawl assembly and rotationally lock the pawl assembly to the dial such that rotation of the dial in a locking direction rotates the pawl assembly in the locking direction, the first projection for engaging a third outer arm of a first pawl of the pawl assembly and the second projection for engaging a third outer arm of a second pawl of the pawl assembly;

the pawl assembly in connection with a housing, and the pawl assembly comprising the first pawl and the second pawl, wherein the first pawl and the second pawl are reversible, and each of the first pawl and the second pawl comprises a body with: (i) a first, inner arm for selectively coupling to a spool, (ii) a second, outer arm having a ramped projection for engaging a toothed peripheral edge of a housing and incrementally tightening the spool as the dial is turned in a locking direction in a first, locked position; (iii) the third outer arm for engaging the dial, and (iv) a slot formed between the first, inner arm and the second, outer arm, the slot allowing the first, inner arm and the second, outer arm to move independently;

the housing receiving the spool, and the housing having the toothed peripheral edge, the outer arm of the pawl assembly engageable with the toothed peripheral edge; and

a base member coupled to the housing;

wherein the rotary closure system has the first, locked position and a second, unlocked position;

wherein, in the first, locked position, the pawl assembly engages the spool and the teeth of the housing; and

wherein, in the second, unlocked position, the pawl assembly disengages the spool.
