Ernst Manufacturing 8481 Socket Boss 3-Rail Tray – Twist-Lock Socket Holder, SAE/Metric, Made in USA

Organize your socket collection with the Ernst Manufacturing Socket Boss Universal Twist-Lock Tray. This 19-inch rail system is designed to adapt to your toolkit needs, letting you load, unload, and reconfigure sockets as you work. Three rails come in the box, each equipped with flexible clips that hold sockets securely, even when you tilt or move the tray.

Key benefits include a modular setup that accommodates different drive sizes and socket counts. You can add or remove socket clips, swap out drive sizes, and even add ratchet or extension holders.
