How to Install and Set Up Your Locker

Align and Secure to Your Cabinet

Customize the Interior Shelving

Once mounted, you can adjust the three shelves to the heights that best suit your tool collection. Use the fixed shelf for consistent spacing and place your most frequently used items at eye level for easy access.

Connect Power for Charging Tools

Route a power cord through the back to the integrated power port inside the locker. Plug in your battery chargers or light, close the door, and enjoy a clean, powered storage space that keeps tools charged and secure.

Hear From Fellow Professionals

I added this to my 72-inch Series 3 cab, and it was the best move. The extra shelf space is perfect for all my power tools and chargers. The power port is a game-changer—I just route one cord in and keep everything charged. Feels just as solid as the main cabinet.

Needed to clear drawer space for more sockets. This locker did exactly that. The adjustable shelves let me fit my drill press accessories and a big torque wrench. It matches the cabinet perfectly and the lock gives me peace of mind when I'm not in the shop.

Installation was straightforward. It bolts right on, and the powder coat matches my blue set exactly. Having 720 lbs of extra capacity means I can store heavier specialty tools here without worrying about strain. It completes the look and function of my setup.

The build quality is impressive for the price. All-welded steel, no flimsy parts. I use the shelves for my diagnostic scanners and the drawer for specialty sets. It turns my rolling cabinet into a full workstation tower. Exactly what I needed.
