This 47-1/2-inch upright comes with a FastTrack for quick attachment to the rail. Made of premium materials for sturdy, heavy duty construction, the unit is great for adding melamine shelving as well. The unit snaps tightly to the rail for easy installation, offering endless storage configurations. No cutting is required for installation.
