TSO Products M6 Knob Set with Centring Spacers was designed for use with the TPG Parallel Guide System. Featuring TSO’s comfort-grip M6 knobs and custom CNC-machined centring spacers, the kit allows you to keep all TPG T-tracks mounted to multiple TPG Adapters or GRS-16 Guide Rails Squares to avoid having to reconfigure setups for different operations.

Also compatible with other TSO products, such as the Angle Accessory and MTR-18 Precision System Triangle.
