For use with the TPG Parallel Guide System but also compatible with other TSO woodworking accessories, this extra M6 knob set features the same comfort-grip knobs and custom CNC-machined centering spacers found in our TPG kits. This spare knob set is useful if you own a TPG Parallel Guide Kit and prefer to keep all of the T-tracks mounted to multiple TPG Adapters or GRS-16 Guide Rail Squares. These M6 knobs can also be used with other TSO products, such as the Angle Accessory and MTR-18 Precision System Triangle.

Note this M6 knob set cannot be used with the Reversible TPG FlipStop v2.0 (or the original TPG FlipStop) as those M6 knobs feature a longer thread.

  • 4 Qty. Comfort Grip Star Knobs

    Excellent product , much better that the previous product . The new knobs have metal centering spacer . The previous model had plastic and would not center sometimes and would damage easily if not careful
