The #10 spiral zipper tape (39 g/m) is the strongest model among coil zipper tapes, designed for heavily used outdoor products such as bags, backpacks, suitcases, and tarpaulins. Its wide, durable fastening chain ensures resistance to heavy loads and the daily challenges of travel. Available in five colours – red, khaki, graphite, white, and black – in 100 m rolls, it allows you to create zippers of any length when paired with a matching non-lock slider. At Berotex, you’ll also find a wide selection of sliders – from standard to extra-strong and reversible – as well as durable waterproof polyester fabrics (1680D) and Oxford quilted materials, perfect for complementing your suitcase or bag project.
