Clamp the track incline accessory to the edge of the table in two places as shown.

Clamp a small universal clamp to the other end of the table for the elevation clamp. Use a ~2 m rod for elevating the track. Insert the rod into both the table clamp and the clamp on the track. Make sure that the clamp on the table is tight. Keep the track clamp loose until the track is position where desired then tighten it.
