Max shipping height is 86" with a max height of 105" with the Z all the way extended and does NOT include the machine resting on leveling pads. The leveling pads are an additional 3.5" of height. Parts from the top of the machine can be removed prior to shipping in order to pass through lower structures, but check with your local HFO if purchasing new for a complete run down on how the machine can be broken down to fit through your opening. Typically they will do it at their showroom prior to delivery, but if you are purchasing used make sure the work is done by a reliable source.
