A new and improved way for assembling your pen parts. Simply flip the spacers out of the way and bring back the spring-loaded mandrel for the length of the components into the position. The self retracting mandrel will then apply enough pressure to help holding the components together up against micro-adjustable press jaw. No more screw/unscrew knobs for length adjustments.
KEY FEATURES:
• Steel handle and pivots deliver up to 300 pounds(136 kg) of pressure
• Quick-flip spacers allow pressing different lengths up to 146 mm
