The Retention Hook allows the user a convenient low profile means of securing items such as gloves, chem lights, and flex cuffs to any belt. With two mounting styles; Belt mounted and Velcro Inner/Outer belt mounted. The Inner/outer belt mount is meant to work with belt systems that use loop on the inner belt and hook on the outer belt. If your Inner/outer system uses hook on the inner belt and loop on the outer belt our standard belt mount will integrate perfectly.
