The 931 A-Tac 1 Belt Keepers from Aker lock your duty belt to your belt, preventing it from moving around uncomfortably as you move. They are made from heat-molded ballistic nylon, making them extremely durable and wear-resistant for a long working life. They can be used horizontally and vertically, and feature a dual fastening system for additional security. The two hard action snaps are backed up by a hook and loop section inside the keeper, preventing them from coming undone during use. The keepers fit a duty belt of 2 or 2.25 inches. Each pack contains four keepers.
