Add additional stability and security to your DEWALT® storage racks with the Floor Mounting Kit. This pack of 4 durable steel mounting plates replaces the existing glass-filled nylon feet of your DXST10000, DXST4500, or DXST4500-W storage rack. Easy to install, each mounting plate is independently adjustable which allows you to compensate for uneven floors that would otherwise cause twisting of the shelves and can compromise the strength and rigidity of your storage rack. Each of the 4 plates features 3 holes to allow you to use the 12 concrete anchor wedges (included) to secure your rack to any cement floor for additional security.
