Ozito track square

This is a track square used on the Ozito track purchased from Bunnings in Australia. this track is less than half the price of other tracks, but it has a different profile, since the creation of this model.I have also modified an existing model to adapt my circular saw to this profile. Here is a link to the product. https://www.bunnings.com.au/ozito-1400-x-180mm-plunge-saw-guide-rail_p6290616?srsltid=AfmBOor-iRC-xSPHAhgtvgfGkBi_jLVkjJYLar5as4vCINz0BLoD--t2
