Snap-on's KRL7065 Mr. Big Roll Cab offers 30 drawers in 13 different sizes, more than 79,000 cubic inches of storage space, and 12' of workspace in living up to its name as "Mr. Big". The unit's drawers range from 2" to 6" in height and are 27" from front to back, with the 5 extended-width drawers measuring more than 49", and reinforced with metal stiffeners to reduce sagging. The extended-width drawers are 4" or deeper, and feature double ball-bearing slides that can support up to 450 pounds of tools and equipment. All drawers also come with non-slip liners. The roll cab itself is constructed from nearly a ton of steel, and is welded at each seam for added durability. Additional roll cab features include a removable stainless steel work surface, 8 heavy-duty locking swivel casters, and Snap-on's Lock 'n Roll™ system that prevents unwanted drawer opening. High security tubular locks and an interchangeable lock core offer additional security benefits.
