Capitalize on maximum configuration possibilities with the Socket Boss Universal Twist-Lock Socket Tray from Ernst Manufacturing, now in a high-visibility color that’s easy to see in low light conditions. Versatility is a must for organizing any socket set. Individual rails can be removed or switched for customization. Add or remove socket clips, label socket sizes with I.D. stickers, trade colors, swap out drive sizes, add ratchet and extension holders: the options are limitless for organizing your own set of sockets. Perfect for storage in the drawer, on the bench, or on the go. This compact set fits a large set of tools using a small amount of storage space. It’s easy to grab and go, with handles on each end. Twist-Lock clips keep sockets secured for transport and prevent tool loss. Even upside down, sockets are locked in tight. Socket rails are locked in the tray for security and unlock with the push of a button. Universal socket rails have also been improved with molded end stops and extended space for sockets. The full length of the 18-inch rail can be loaded with sockets. Ernst recommends different colors (red, blue, or high visibility yellow) for easier identification between SAE and Metric tools.
