The Black Diamond CarbonLock 23" Rolling 1-Drawer Toolbox combines mobile storage with fast access to the tools you use most and features a 70 lb. internal load capacity and a 250 lb. total carrying capacity. The large drawer provides storage for larger tools and equipment, while an independent drawer latching mechanism and heavy-duty metal ball bearing slides deliver smooth operation and secure closure. Rugged 8" wheels with a steel axle and ball bearings roll easily across rough surfaces, and the removable telescoping handle makes transport and storage simple. Exterior accessory rails add expandable functionality, while the CarbonLock auto-connect stacking system securely locks additional toolboxes and organizers in place.
