Ronstan Rope Clutches - Line Constrictor

Unlike all conventional clutches the Ronstan Constrictor system does not crush the rope between two metal surfaces. Instead, the loaded rope is held securely in a textile sock, itself attached to an anchor base. The rope runs freely through the sock in one direction, but is gripped instantly within the sock when running out in the opposite direction. This constrictor effect, patented by COUSIN Trestec, provides increasing holding power as the load increases.
