The 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 Agata bench capper height is an easy manual adjustment, set by using the black button on the side. For best capping results, the capper should be mounted on a bench or work table using the mounting holes on its base.
