Step 4: Which Slider Type?

Locking: Slider stays in place unless the tab is pulled. Recommended for bags, cushions, apparel — projects where you need the slider to stay put until unzipped.

Non-Locking: Slider will move if any part of the slider is pushed or if zipper teeth are pulled apart. Recommended for projects where you need to quickly and easily separate the zipper, like a genoa sleeve or spinnaker sock. 

Single Pull: Sliders have a pull on only one side. Recommended for projects you only access from one side, such as cushions, bags, apparel and canvas covers.

Double Pull: Sliders have two pulls — one on each side. Recommended for projects you can access from either side, such as marine enclosures and tents.
