8RCW (DOUBLE COIL)

“RCW" is a zipper with double racquet coil chain. The racquet coil was designed for bags and backpacks, where resistance to abrasion is required.
The double element structure more than doubled the chain's resistance to puncture compared to the usual 8RC zipper.
It prevents the chain from being easily punctured with pens and other similar objects.
The anti theft zipper.
