Bosubi – Racquet Coil
YKK’s Bosubi range is based on a durable water-repellent and anti mould treatment. This reduces water seepage, as well as wicking and zipper tape degradation when used in outdoor or maritime environments.
YKK’s Racquet Coil® has been specifically designed for applications (Luggage and Tents) where resistance to abrasion and performance is a must. Racquet Coil® chain is made of spiral plastic elements which feature a unique oval shape. This design strategically places the sewing thread (which attaches to the zipper tape) in an indentation on the oval, thus protecting it from being torn and exposed. The sliders are engineered to ensure the perfect reciprocation of the zip.
