#7 & #8 are used for gear. Uses: tents, jackets, luggage

TOOTH SIZE the smaller the number the smaller the tooth
size: ie. #5 is smaller than #10 and thus not as strong.

CONTINUOUS ZIPPER a length of zipper, either coil or
tooth style, sold by the yard. Allows you to make and
customize your own zippers. At least one end must be
sewn closed. It cannot be used to make separating
jacket zippers.

ZIPPER TAB the zipper pull (slider) on the zipper [Note:
the zipper tabs from one brand (ie: YKK brand) are
usually not interchangeable with other zipper brands
(ie: Maxi brand zippers, etc.)

(1) single tab-a zipper tab with only one pull

(2) double-reversible tab-a zipper tab with a pull on both sides of the tab. Uses: sleeping bags

(3) non-locking tab(NL)-a zipper tab which slides easily and
has no internal locking mechanism to hold it in
place. Uses: pockets, luggage, tent doors

(4) locking tab(L)-a coil zipper tab which has an internal
locking mechanism to hold the tab in place
ie. trouser zipper

(5) key locking tab(KL)-a zipper tabs which locks and
unlocks with a removable key. Uses:security
envelopes, luggage

For many projects it’s your preference which style you choose

ZIPPER ANATOMY

WHY MAKE YOUR OWN ZIPPERS:

There are a number of reasons why you would want to make your own zipper using
continuous coil or continuous tooth zipper length.

1. By doing so you can customize the length and style of the zipper you want ie: one
way non-separating, two-way non-separating or one-end-closed. [NOTE: The

only style of zipper you cannot make with continuous zipper is a one-way or a
two-way separating zipper-like a jacket style zipper].
2. When you make your own zipper you can select the style of zipper tab you desire:
non-locking, locking, key locking or double reversible. See the zipper terms box
to determine which style of tab to use.
3. Often times it is more economical to make your own. To determine how much to
buy just add 2" to the desired length you want the zipper to be (1" extra for each

end) ie: if you want a 70" zipper you will need at least 72" of continuous zipper.

SHOULD YOU USE TOP & BOTTOM STOPS:

Top and bottom stops can be optional. The purpose of zipper stops is to keep the
zipper tab from pulling off when the zipper is in use. If an end of the zipper is sewn
into a seam you may choose not to attach top/bottom stops because the seam will act
as the "stops". When using zipper stops, bottom stops are attached to one end of a

one end closed zipper and both ends of a one or two-way non-separating zipper. Top
stops are used at the top end (the "open" end) of a one-end closed zipper.

WHAT SIZE TOP & BOTTOM STOPS SHOULD YOU USE:

For #5 and #8 coil and #5 tooth zipper use #7 top and bottom stops. For #10 coil and
#10 tooth zipper use #10 top and bottom stops.

HOW TO ATTACH A ZIPPER TAB

1). On one end of the zipper tape, part the zipper teeth about 2". 2). Insert one side of the zipper about 1/4 " into the curved end of the zipper slider. [NOTE: On double pull sliders place the slider so that the angled portion of the flange is up]. 3). Insert the other end of the zipper into the slider. To prevent misalignment on the other end of the zipper line up the short ends of the zipper tape evenly. 4). Firmly holding both zipper halves slide the pull onto the zipper teeth. It may take several attempts to line up the zipper teeth and to prevent a bulge on one side of the zipper tape if the teeth are misaligned. [NOTE: When putting two pulls on the same zipper tape, attach the second tab on the opposite end of the zipper tape using the same method as above].
