Zipper tricks and techniques
Choosing the right type of zipper for a project depends on the application, desired longevity, and environmental conditions. Working with zippers in difficult situations requires patience and expertise, as this article explains.
Features that matter
Plastic zippers are popular among marine fabricators because they last longer and are easier to work with, while metal zippers can be difficult to repair if a tooth breaks off.

Longevity is key

Metal versus plastic
Metal simply doesn’t last long in saltwater spray and corrodes over time, so a metal zipper with a metal slider can result in a completely seized zipper slider. The most common are plastic zipper teeth with either Delrin (plastic) or metal sliders.
Pre-positioning zippers prior to sewing is recommended by Sailrite Enterprises Inc., as sewing too close to the zipper teeth will prevent the slider from moving freely, and care must be taken to sew the zippers with enough clearance to allow the slider to move freely.
