Starter Bay : You can use this bay on its own (it has four legs) or to start a run of several bays of gondola shelving.
Add On Bay : These bays only have two legs as they attach to your Starter Bay to create a run of two or more gondola bays.
Measuring for a gondola bay : The gondola bay is measured from the floor to the top of the gondola. It has screw feet which allow an extra 50mm to allow for an uneven floor. The base shelf depth is measured from the back panel to the front edge of the shelf.
