(CKR310) Made in Italy. Well suited for the home winemaker who is in need of an easier/faster method of corking wine bottles. You can cork up to 150 bottles an hour with this unit. Very well designed. It will insert a size 9 straight cork with little effort. Heavy metal construction with a 3 piece brass compressing iris for even compression of the cork on all sides, no cork damage. We recommend this unit for anyone who is bottling more than 5 or 10 gallons at a time.
