The LG2020 is a unique design, as it is one of the only pieces of battery powered equipment that functions safely and securely on a range of staircase types. This includes spiral staircases, flared stairs, narrow stairs, slim aisle spaces - such as those on aircrafts - and even awkward and small landing spaces. It is a more specific item of kit but if these are issues ever encountered - this is the perfect equipement to solve the problem.
