The oktober model 7 can seamer
The Model 7 Oktober Can Seamer is capable of seaming almost any aluminum beverage can size. Each seamer includes one tooling set, and optional interchangeable tooling sets are available for end sizes from 200 to 300. This means that (for example) the same Model 7 Oktober Can Seamer could seam a 16oz can and a 32oz Crowler™ can with an easy tooling swap. Each tooling set includes standard lower adapters; other lower adapters for other size cans are available as well Here.
