The Fit System Corner Connector comes standard with one shelf, one leg and one 3" Caster.
Use to connect Standard Units only. Cannot be used as a stand alone Unit.
Product ships unassembled, with all the necessary tools.
If you're putting 5" casters on the rest of your Station, be sure to add one more for your Corner Connector. You can find one in the Fit System Accessories section.
Corner Connectors take up more space than you may expect. Add 44.25" to the width of each Standard Unit in your configuration to determine the amount of space required.
