Economizing warehouse space is a very important goal for most companies.  As a result, aisle widths tend to be on the narrow side.  It is very important to know the width of your standard aisles so that you can confirm that the minimum aisle width recommended for a Stacker unit falls within those dimensions.  If, for example, your aisles are 84” wide and the recommended aisle width for a specific stacker is 96” there are 2 choices to consider: either increase your aisle width or find another stacker that will effectively maneuver within an 84” wide aisle.
