10"-24" ALL PURPOSE or #3 ZIPPERS
These are closed bottom or finished individual zippers.
Each is cut to length & finished with bottom stop, top stops & a short, auto-lock slider.
Why is an auto-lock slider or heads the best for most applications?
There are 3 basic types of sliders: locking, non-locking & auto-lock.
Locking: Has 2 little prongs on the underneath side of the pull that physically push into the zipper to keep the slider from moving.
Non-locking: No mechanism to keep the pulls from moving.
Auto-lock: A little spring is inside the slider that is activated when you pull up on the pull & when you quit pulling then there is a little lock that drops on the coil to keep the zipper from opening.
I like the auto-lock because you don't have to think about pushing down on a locking pull. It just happens. Non-locking works on bags or sail covers, but not on your jeans!
