YKK® Heavy Duty Swivel Snap Hook is used as a webbing attachment point to connect with D-rings or other hardware. This snap hook is made from polyacetal, a strong plastic that bridges the gap between metals and ordinary plastics in stiffness, hardness, dimension, stability and toughness. Snap hook allows for rotation at the base and prevents accidental disconnection from D-rings and other hardware. Use for straps on bags, luggage, sports equipment and more.
