False Bottom/Grain Press from Brewers HardwareMore Info
From the product description, check product page for current description, price and availability:
These were one of the original design false bottoms for our kettles, but are now discontinued. They are 15 5/8″ wide, so they will fit any kettle with an inside diameter greater than that.
These false bottoms do not come with legs. Because of this, you will need to supply your own or instead it could be used as a press to help push out remaining wort in the grain.
As of this posting, Brewers Hardware has a limited number of these marked down 25% to $30. Check Brewers Hardware for current availability.
