These eyelet gliders are suitable for curtains made of lightweight fabrics, used with internal tracks that have a track opening between 5.4 mm and 9.5 mm. Their eyelet is aligned with the direction of travel and, together with the curtain hook, ensures a neat drape. Since these gliders don't require much downward space, the curtain tape should not be attached too far below the hem. The pack contains 100 eyelet gliders.
