The Semi-Automatic Portable Chuck Capper is manufactured with an easy to use height adjustment which allows the capping machine to handle many different size containers.

A simple ratchet handle is used to adjust the height of the chuck capper.  For smaller containers, simply loosen the handle and slide the chuck to the correct position over the container, then secure the capping head by tightening the ratchet handle.  When you are ready to cap larger containers, the same process is used, securing the chuck capping head slightly above the larger container.
