The Black Diamond CarbonLock 23" Rolling Toolbox is built to move serious weight without slowing you down on the job. With a 150 lb. internal load capacity and 250 lb. total carrying capacity, it's designed to transport heavy tools and equipment with confidence. Constructed from heavy-duty impact-resistant polymer with rugged latches and metal hinge pins, and backed by an IP65 rating to help protect against dust and water, it's ready for harsh jobsite conditions. Eight-inch all-terrain wheels roll smoothly over rough terrain, while the telescoping, removable handle makes transport and storage easy. Includes a removable carry tray to keep smaller components organized and within reach, while exterior accessory rails allow you to attach hooks, holders, and add-ons for expanded functionality. As part of the CarbonLock modular system, the auto-connect stacking mechanism securely locks additional CarbonLock toolboxes and organizers on top, so you can build your perfect setup.
