I have used the Gilbert Termination Installation Removal Tool on the following Terminators: GTP, PCT International TPG, PDI Inc PTP-59, PTP-59LR, Sinal Vision, Inc SV-LT & SV-LTA, TR 75 GTL and Im still going to try more. So far so good. I ordered mine and use it with a T-handle 1/4 driver. Works good and feels right...
