Spring-loaded cord stops that secure a single drawcord with a simple press-and-release action. Use them to add adjustable closures to jackets, hoodies, anoraks, gym bags and casings on home-sewn accessories. To install, compress the top, feed the cord through the hole and release to lock; the internal spring holds firm to reduce slippage. A clean, low-profile solution for garments and bags that need quick, tool-free adjustment.
