If you are in Australia or another country that doesn't stock TSO Products, why not get a few people together to make a large order to reduce the shipping cost?

Power loc dogs from TSO products are going to help you hold jigs and connect in as many ways as your imagination can devise when using a 20 mm dog holed bench such as my own Stanton bench, Ron Paulk's bench or the Festool MFT-3.

The thing that sets the Power loc dogs apart is there is no need to have access to the underneath of the bench you are working on. Fine and exact engineering has ended up creating a 20 mm stainless steel dog that can be secured from above the bench, even if your bench is a torsion box design like mine!
