15 gallon pot 18 gauge with one 1/2" NPT welded female coupling. Perfect for a 1/2" ball valve assembly on the outside and a bazooka screen on the inside. Pot measures 16" (diameter) by 18" (height) and weighs just over 12 lbs Inner Dimensions are 15.625" wide x 17.875" high The pots are wonderful, the lids are a little cheap - Hey, we are boiling in them, who needs a stinkin lid anyhow? As a side note - these are $109 pots - please do not expect a $259 Polarware. Some small dents or nicks are expected.
