New double ended hybrid rail square. And the new 250mm ultra insert plate

Description

I first designed the ultra rail square back in 2019 by the request of my costumers. But now i am only making the new double ended hybrid square i have designed it in two half’s so you just remove the four screws from underneath and add the 250mm ultra plate and reconnect it all with four bespoke thumb screws and you now have the fc hybrid ultra rail square . Which will be around 620mm long giving you a longer more accurate  square as you have a much longer square edge.
