How tall is the B266?

How tall is the NB cart with a B266 bolted to the mast?

The B266 post itself is 18'' off the mast, thus making an NB cart height 61". Please keep in mind, however, the monitor could make the height higher based on where the B266 is secured to the post. The height of the monitor could add height as well. The NB carts dimensions are: 26" Long X 24 " W and 43" High.
