Slider Puller For Round Lanyard with solid grasp and a spring-loaded design, it can maintain a firm grip on whatever it's used for, and it's simple to set up and operate. Our cord locks are compatible with a wide range of drawstrings and cord types. Shoelaces, pack drawstrings, pants closures, lanyards, luggage, apparel, backpacks, sportwear, tents, and a range of outdoor and gym equipment are all examples for widely use. A plastic cord lock is used to tighten drawstrings without the need of knots. When mountaineers' fingers are covered in heavy gloves, cord locks help them to quickly tie clothes and camping equipment in frigid circumstances. A barrel, a toggle, and a spring are the three main components. Tension is released when the cable lock is squeezed together, allowing the cord lock to easily glide up and down the cords. When the strain is released, the cord lock remains in place.
