The first track has a first profile and the second track has a second profile. The first and second profiles are releasably engageable to each other. The first track has one or more spaced primary notches interrupting the first profile. At least one slider is inserted onto the first profile via a respective one of the primary notches. The slider is adapted to engage and disengage the first and second profiles in response to movement along the zipper. The second track may have one or more spaced primary notches interrupting the second profile. The spaced primary notches of the second track are generally aligned to respective ones of the primary notches of the first track. At least one slider is inserted onto the aligned pairs of primary notches via a respective one of the generally aligned notches.
