Round spring-action cord stop designed to tighten drawstrings and prevent cords from slipping into casings. The compact, smooth-edged housing is comfortable to grip and allows one-handed adjustment—ideal for jackets, hoods, gym bags and DIY accessories. The internal spring provides reliable bite on braided cord or elastic, reducing the need for knots and making garments easier to put on and take off. Durable, lightweight plastic stands up to daily use indoors or out, from schoolyards to campsites, and is simple to re-thread when replacing worn cords.
