Divisible Spiral Zipper YKK Cobalt 80CM

Divisible Spiral Zipper YKK Cobalt (918) 80CM Nylon

This zipper stands out straight away with its deep cobalt blue colour, a shade that reads as both fresh and bold. The spiral-shaped teeth are fine and uniform, delivering smooth up and down movement of the slider. The broad, sturdy slider with its recognizable YKK marking sits nicely against the tape and gives an immediate sense of quality. Thanks to the divisible construction, you can completely separate the two halves from each other, which is handy when inserting or replacing it in a project.

What is a divisible spiral zipper

A divisible spiral zipper consists of two separate zipper strips with plastic spiral-shaped teeth, which you only join together via the slider. This differs from a closed zipper, where the bottom stays joined. It makes this zipper suitable for garments you want to open completely flat, like a vest or jacket. The nylon version is lightweight, flexible, and stays smooth to operate even after heavy use. You'll find this type of zipper in the category divisible nylon zippers YKK, where multiple colours and lengths come together.

Uses and projects

At 80cm long, this zipper is generous enough for larger sewing projects where you need full opening capability. Think about:

• Summer jackets and vests you want to open completely
• Softshell jackets and outdoor clothing
• Sleeping bags where the zipper needs to come undone
• Large bags and backpacks with a continuous opening
• Cushion covers and home décor with a removable front
• Sportswear such as training jackets
• Ponchos and capes with a front opening
• Handmade covers for furniture or equipment

Material and properties

This zipper is made from sturdy plastic spiral teeth on a robust polyester tape, a combination known for its durability and flexibility. The spiral structure makes the zipper lighter than a metal alternative, while still holding up well to pulling force and frequent use. The slider glides smoothly over the teeth without catching, even when zipped up and down quickly.
