Safariland ELS Kit
This kit includes two pairs of Safariland's ELS mounting devices, the necessary fasteners and an allen wrench (as the picture indicates).
The ELS is a great little part for mounting your accessories to a variety of places on your gear. This system is fantastic for mounting magazine cases, pouches, and accessories to your belt, molle vest, or leg mounts. Their versatility allows you to quickly and easy try different configurations to find the ones that work best you in any situation.
