Stannah 420 DickoParticipant March 18, 2022 at 8:12 pm Hi, is it possible to switch a circa 10 year old Stannah 420 from one side of a straight stairs to the other? Also, does anyone know of an independent stairlift fitter in the Farnham, Surrey area? Thanks Simon Viewing 0 reply threads You must be logged in to reply to this topic.
