Grace Company Continuum Frame Two Foot Extension 

This extension only works on the Continuum frame made by the Grace Company.  It includes the rail and table top pieces so you can set your Continuum frame up as a seven foot or 12 foot table depending upon the length of the frame you have now. This basically makes it so you have two middle legs if you set your frame up to 12 foot size. With the 12 foot length you can have a maximum quilt size of at least 132 inches.
