This socket organizer bundle from Ernst Manufacturing includes two 13-inch socket rails to provide versatile storage solutions for your mechanic's toolbox. The first rail comes with 14 red 3/8-inch twist lock clips to securely hold standard and metric sockets upright and make them easy to identify, access, and replace. The second rail features 14 blue 3/8-inch twist lock clips for additional customizable socket storage. Both rails utilize Ernst's patented Dura-Pro twist lock system which allows you to lock sockets in place with a simple 1/8 turn. The smart tension keeps sockets secured without having to fight to remove them. The rails can also be mounted vertically to maximize storage space. With the ability to add, remove, and reposition the clips anywhere along the rails, this set allows you to customize your socket storage to fit your specific needs. The bundle includes 96 fractional/SAE and metric size labels for easy tool identification. Made in the USA by Ernst Manufacturing, these high-quality socket rails integrate seamlessly with other Ernst storage solutions for a unified, professional-grade toolbox organization system.
