This really is a multi-purpose link, which allows you to change hook links or leads in the blink of an eye. The shape of the clip makes it very easy to attach and detach things such as leads, swivels or hook link looks, even with cold hands or in the dark. Use a Tapered Sleeve, or similar, over it for a neater, more secure finish, especially when using to attach a hook link. The Kwik Link has a non-reflective finish. Available in small or extra small sizes, in a pack of 20.
