The TGP Adaptor is an economical and reliable means for attaching a TPG-30 or TPG-30/50 Parallel Guide track to Festool, Makita and Triton guide rails. The adaptor can be used on RH and LH tracks, and is secured using the knobs from the Parallel Guide kit. TPG Adapter secures to your guide rail using the same innovative keystone alignment feature and torpedo nut found on the TSO GRC-12 Guide Rail Connectors, ensuring rock-solid attachment that's easy to install and remove. The TGP is intended to be used when the GRS-16 Guide Rail Square has not been purchased beforehand. Note: Previous versions of the TPG Adaptor included Comfort Grip Knobs and Centering Spacers, along with a 3mm Ball-Hex Driver. These accessories are now included in the TPG-30 and TPG-30/50 Sets, and no longer included with each TPG adaptor.-bg
