The E-Zee Trim case trimming system allows the user to trim cases by hand or with a power attachment (included) to precise pre-set length with no adjustment of measuring needed. The trimmer comes with a case locking device, cutter, trim-to-length pilot, cutter head, and both hand and power trimming adapters. It works with any standard shell holder. The E-Zee Trim assembles in seconds and you are ready to trim cases.
