How do you recommend to install reducers and corners for 2-1/2" tiles? How to fix it in place? There is no way to use Blok connectors, so I am stuck with it.

To adhere the ramps and corners you will want to use our polyurethane glue or seam sealer. Just apply the glue to the side that butts up to the tile, press and hold and the ramp and corners will bind to the floor.
