1.The tension range is large, using the latest wire jump-prevent structure;

2.Tension scale is precise with tension value, which is convenient for testing of several machines.
3.Hole diameter for installation is 16mm, vertical type, anti-tension rod with big swings and long wire reel.

4.Tension is generated with multi NS magnetic field and no mechanical friction, and with stability tension;

5.The main components :O-ring and all imported bearings with supurb quality.
