Ernst 3 Rail Twist Lock Socket Boss 8", Blue – 1/4", 3/8" & 1/2" (8551)
Versatility is key when it comes to organizing your socket set. The Ernst Socket Boss® gives you maximum flexibility with its fully customizable design. Each rail can be removed, rearranged, or swapped to suit your setup.
Add or remove socket clips, label each socket with I.D. stickers, switch colors, or attach ratchet and extension holders — the options are endless.
This compact organizer fits a large number of tools while taking up minimal space. Perfect for storage in a drawer, on your workbench, or on the go. With handles on each end, it’s easy to grab and carry, while the Twist-Lock clips keep sockets securely in place during transport.
Customize your setup even more with Ernst socket accessories. Your sockets stay locked tight — even when turned upside down! The socket rails lock firmly into the tray for extra security and release easily with the push of a button.
The improved universal socket rails feature molded end stops and extra spacing for larger sockets.
