The Adjustable Trigger is the perfect spray top for almost all 16oz and 32oz bottles, plus many other sizes. The Adjustable Trigger's tube is flexible so it helps you get to the bottom of just about any bottle and not waste product. Just twist this top on to your current bottle and you're ready to start working. The Adjustable Trigger can spray a full stream or a fine mist by simply twisting the nozzle. This trigger is flexible and extremely durable so you will be using it for years to come. They also works great with our dispenser bottles if you need both a bottle and trigger.
