The Socket Roll SAE Pro is designed to keep sockets and accessories secure and easy to transport. It's available in three SAE versions: 1/4, 3/8, and 1/2. Each offer easy-to-read drive socket sizes for quick access. The organizers are made in the U.S.A. with military grade elastic material that prevents premature wear and stretching while keeping tools dry and protected from fluids. The SAE Pro measures 14" by 14.5" rolled out flat and 3.5" by 14" rolled up. The organizers have 21+ socket sleeves, deep and short sizes, with additional sleeves for accessories. The base fabric is a double layered nylon with PVC backing that features a plastic insert behind each socket row for added strength and protection.
