The Super Agata bench capper is easy to set up and use. The standard bell has a magnet to hold the bottle cap. Just put the beer bottle on the plate and pull down on the handle. The cap is crimped and sealed. The Super Agata bench capper height is self adjusting. This deluxe model sets itself automatically for the bottle height. For best capping results, the capper should be mounted a bench or work table using the mounting holes on its base.
