The Chuck Hook

 The Chuck Hook is a patent-pending, lightweight, innovative 3D-printed accessory designed to easily hook onto a backpack strap, without having to adjust the strap, and hook around the strap of any item normally carried on your shoulder, such as a rifle sling or camera strap. This item was created out of the need to prevent a rifle sling from sliding off my shoulder while hiking but also allow the rifle to be quickly handled when needed. The Chuck Hook weighs less than 0.5 ounces and is available in four colors. Made in the USA with materials made in the USA.
