Designed to slit as narrow as 1.5 in., Model DRS has completely guarded dual blades that, retracted or extended, reduce chance of operator injury. Because blades are held in place magnetically, either of them can be installed or removed without tools. They can also be changed without interrupting slitting process. Slitter mounts on standard dovetail bar, allowing retrofit to non-Parkinson winders. Other mounting options are also accommodated.
