Versatility is a must for organising any socket set. Capitalise on maximum possibilities with the Socket Boss Storage Rail from Ernst! Individual rails can be removed or switched for customisation. Add or remove socket clips, label socket sizes with I.D. stickers, trade colours, swap out drive sizes, add ratchet and extension holders. 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. Easy to grab and go with handles on each end. Twist-Lock clips keep sockets secured for transport and prevent tool loss. Add Ernst socket accessories for your own custom set. Even upside down – sockets are locked in tight! Socket rails are locked in the tray for security, simply unlock with the push of a button. Made in USA.
