You might be having a small problem to take off the teeth of your Crown zipper when you need to shorten it. Because Crown Zipper teeth are molded right on the tape, not clamped on like any other manufacturer's zippers such as Talon, Conmar. . . . This molded teeth method definitely made Crown Zipper tougher than the other manufacturer's zippers. But on the other hand, it will be also tougher for you to take off the teeth at your Crown Zipper. Refer to following instruction for your shortening Crown zippers.
[ How to take off the teeth. ]
Before you start to shorten your Crown zipper, practice some times using extra part of your zipper.
1) First, cut the two points of (A) by a nipper or any tool without damaging zip tape. (Refer to the left illustration.) It usually needs to take off teeth 1" long.
At facing to the zipper oppositely, the left top tooth should be higher than the right top tooth when you complete the shortening. (Refer to the left bottom image.)
2) Turn off the divided 3 parts of (B) gently from the tape by a needle nose pliers or any tool without damaging the zip tape.
[ How to put the 40s style top stops on the Crown Chevron zipper. ]
At facing to the zipper oppositely, the lower top stop (A) is for the left top of the zipper. And higher top stop (B) is for the right top of the zipper. (Refer to the left image.)
Put them in the zip tape just along the top teeth and press them properly by a needle nose pliers or any tool without damaging zip tape. (Refer to the left bottom image.)
