in front and under the zip slider using the
back of your hand and cup the zip slider
underneath with your remaining 3 fingers.
Use this action for opening or closing. Keep
the fabric clear of the zip slider - zip and unzip
slowly.

slightly over time. This can be exaggerated
quickly if fabric is caught into the zipper.
When this occurs the slider does not
compress and interlock zipper coil teeth
tightly enough and the zip bursts open or
does not close. To fix this, simply undo the
zip and with the slider at the end of the
zip lightly crimp the jaws of the zip slider
together with a pair of pliers.
CRIMPING INSTRUCTIONS FOR A ZIP
SLIDER
The most common reason why zips burst open
is that the zip slider does not close the coil
tight enough. Commonly wear and tear or
fabric jamming will cause the gap marked “A” to
increase, see Figure 29.
By gently “crimping” the slider together at
points “B” and “C” with a pair of pliers, gap
“A” can be adjusted most times to its correct
opening, see Figure 29. Crimping in other
planes is worth a try if “B” and “C” fails to rectify
the problem. This crimping is done when the
zip slider is still attached to the zip coil and is in
the fully open position.
