2-Piece Screw Cap


  • $7.00

Top/Strap for newer Boulder, Bigfoot, Growler and Twist bottles

The top measures 2 inches tall and 2.75 inches in diameter. This part comes as one piece and is sold as a unit.

The first time you use this top, please screw down very tightly, so it will form and set a tight seal. 

These tops will fit on any of the flip straw top bottles with stainless steel threading if you would like to convert your bottle to the "Boulder" style.
