The high-power crimper/decapper tools from Trajan have interchangeable sets to fit different cap sizes for vials. They are ergonomically designed to reduce effort and arm strain. The capping/decapping sets are available in sizes of 8 mm, 11 mm, 13 mm, and 20 mm, including flip-off caps. This tool stores separate programs for different caps and vials, and it is strong enough for all steel and magnetic caps. It includes convenient controls on the top to adjust crimping and an optional mounting kit.
