What Are Open-End Zips?

An open-end zip (also called a separating zip) has a box and pin at the base that allows the two sides to fully detach. This is the standard construction used in jackets, coats, and hoodies. Closed-end zips, by contrast, are fixed at the bottom and used in trousers, bags, and cushions.

Suitable For

Jackets, hoodies, gilets, fleeces, sportswear, children's clothing, craft projects, and garment repairs requiring a full-separation fastener.

    YKK Vislon HEAVY Two Way Plastic Open End Zipper #8 (7mm) Zip Chain 6 Colours/ 4 Sizes Heavy-weight moulded tooth zip with movable bottom slider. Allows zip to be opened from both the top and bottom Teeth Width = 7mm Tape Width = 35mm Choose From 6 Colours 24" - (61cm) 26" - (66cm) 28" - (71cm) 30" - (76cm) 27/2/20 - Please note - YKK describe the Grey zip as Dark Grey when in actual fact it is more like Mid Grey.  Please keep this in mind when making your purchase. I only just took delivery of these zips and was surprised by how well made they are. The teeth on the zip are thicker than the normal 5mm teeth and give it a real chunky look and feel to it. They open at both top and bottom so you can pull the zip up from the bottom to allow you get something from your trouser pocket for example. Theyre made by YKK who are probably one of the best zip manufacturers in the world today and this will explain the price. Its not a budget zip, its quality   Hope this helps   Kind regards   Martin
