Metal sliders with perfectly smooth edges. Most often used for tightening, shortening, or joining. Ideally suited for making luggage (suitcases, backpacks, handbags, bags, and suitcases) or for sporting goods and dog equipment (collars). The parameter values given in the table refer to the inner height/width of each opening and not the overall dimensions of the slider. Choose from sizes 16–50 mm.
