Congratulations on purchasing the GRR-RIPPER 3D Pushblock system. Over 5,000 hours
of engineering, 45 design concepts and prototypes went into making the GRR-RIPPER
the safest, most precise pushblock available. Before using your GRR-RIPPER, read
through this manual to familiarize yourself with the GRR-RIPPER and how it works.
The following is a general overview of the way the
GRR-RIPPER is designed to work:
The GRR-RIPPER uses grooved non-slip
pads (Green GRR-RIP
®
) to hold down and
feed your workpiece through the cutting
element. The tool can be rotated end-
to-end to for use with either the 1/2” or
1/4” Side Leg against the fence.
With the rip fence set parallel to the saw
blade, the GRR-RIPPER glides against
the rip fence to ensure a parallel feed. It
also keeps both sides of the workpiece
in their original positions throughout the
cutting process, which virtually prevents
the possibility of kickback and burning.
With bare-hand feeding eliminated,
finger injury is greatly reduced.
The GRR-RIPPER feeds the workpiece
as the saw blade passes through either
its right or left tunnel. This feature
virtually eliminates the need for bare-
hand feeding when used properly.
The GRR-RIPPER is a protective guard
that you hold throughout the
cutting operation.

The Adjustable Handle can be relocated directly above the cut-line, providing
balanced and concentrated pressure.
The height adjustable Balance Support
accommodates different thicknesses
of stock.
The adjustable Center Leg precisely
supports different widths of cuts, providing
complete control of both sides of stock.
Wooden riser spacers can be added for
use with stock thicker than 2”.
Attach with #8 pan head wood screws
and washers (not included).
A wooden spacer can also be added between the GRR-RIPPER and the fence to
increase the cutting width capacity of the GRR-RIPPER.
Fully adjustable GRR-RIPPER controls wood of different widths and thicknesses.
Adjustable design for your project needs.
