MicroJig T28208 - GRR-RIPPER 3D Pushblock
The pushblock gives three directions of force:
The GRR-RIPPER utilizes Green-GRIP, a proprietary non-slip material that gives you superior gripping power over workpieces and materials from soft to hard woods and even aluminum.
Treaded grooves provide increased traction on the workpiece even with sawdust.
Easily cleaned with denatured or rubbing alcohol. No other push block's grip comes close!
