Precision Pour® collared spouts are a nice cosmetic upgrade from our standard style spouts. The collar covers the threads of a bottle as well as any exposed fins on the spout stem. Also, our collar is locked on to the stem of the spout, this makes it easier to remove the spouts from empty bottles. Because of different sized bottle openings, all of the fins on a spout's stem may not fit into a bottle. That's OK. Precision Pour® spouts are designed this way in order to fit the greatest number of bottles possible. A collar covers these exposed fins and also covers the glass threads that are visible once you remove the cap from a liquor bottle. Unlike other manufacturer's spouts, Precision Pour® collars are locked on to the spout's stem. This means that the collar and the stem turn as one, making it easy to remove the spouts from empty bottles.
