Question about the Valdora Extensions

Does anyone know how the length and rise of the Valdora Extensions?
I am thinking about using a set of these but want to know where my hands will be relative to arm rests…

I have them on a set of 3T Ventus bars. The extensions themselves have a rise of 3.5 cms (taken from the center of the carbon tube under the armpads to the center of the carbon tube at the front where the bar-ends plug in). Mine are 30cms long, but were cut down by Elite - not sure of how long they were to start. Oh…and the SRAM Red shifters are a perfect fit into the Valdora extensions - looks like they were made for them - a must-use.
