YKK proudly presents our new Racquet Coil "RC" zipper.
Especially designed for luggage where resistance to abrasion is a must, the zipper was precision engineered to
meet the toughest performance requirements.
Unique Shape Protects Thread:
The new RC zipper features a unique oval shape that ensures durability.
And, YKK takes the advanced design to the next level by strategically placing the sewing thread (which attaches zipper to tape)
in an indentation on the oval thus protecting it from exposure and from being easily torn(Patent Pending).

Using the Weisenbeck Abrasion Test*, YKK examined zipper chains' durability by rubbing sandpaper against the chain to measure resistance to abrasion.
On conventional chain, after 60 rubs the holding thread was badly damaged.
In contrast, the RC chain withstood up to 100 rubs or more.
