Designed to sit neatly along your bed rails without obstructing rear visibility or occupying valuable cargo room, this low-profile toolbox offers 4.0 cubic feet of reliable storage—perfect for contractors, mobile technicians, DIY users, and anyone who needs quick access to essential tools.
Built from heavy-duty welded aluminum and finished with a Clear ARMOR TUF Powder Coat, this box delivers long-lasting durability while resisting corrosion, scratches, and harsh environmental exposure. Its reduced height gives your truck a sleek, streamlined appearance while still providing ample internal capacity for hand tools, small equipment, and hardware.

At the heart of its security features is the WEATHER GUARD 1KEY Ultralock system. This advanced lock is tamper-resistant and allows multiple boxes—or an entire fleet—to be keyed alike for unmatched convenience. The bold, retractable push-button lock provides instant confirmation when the box is secured, giving you peace of mind on and off the jobsite. With a full weather seal, 90-degree lid opening, enhanced tie-down buckles, and integrated 12-volt access for PowerSync accessories, this low-profile lo-side box is built for both practicality and performance.
