RJS developed the Model 305 tension controller to offer improved creel operation at low tension and can be used for both steel and textile cords. The Model 305 offers a tension range of 0.27 – 2.3 kg (0.5 – 5 lbs.). The same proven principles found in all RJS controllers have been applied to the Model 305, with careful emphasis given to those elements which affect low-tension operation. This model is designed with the control arm roller positioned below the spool.
