Constructed with impact resistant polymers, all-metal ball bearing slides, and metal reinforced corners the 2 and 3 Drawer Tool Boxes are built for ultimate durability. The drawers are designed for easy access to tools and materials no matter where they’re stacked, and both have a 50 lb weight capacity. Users can easily customize the internal drawer layouts through quick-adjust dividers and a locking security bar holds the drawers closed to keep contents secure during transport. New customizable foam inserts and quick-adjust divider sets are also available for increased storage organization. https://www.youtube.com/watch?v=Bv8BK6Ldnd4
