The Graphite Modular 5x4 9U Professional Drawer System (3-Pack) is designed for customers who already know they need more than one drawer position. It gives you three matching units so you can build out a consistent storage wall, bench, or tool zone without mixing sizes or finishes. That makes it a practical choice for workshops that want organised, repeatable access now, while leaving the door open for future mixed-size combinations once real usage patterns are clearer.
